Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable spike-assisting projection plate which enables a spike-replaceable golf shoe to be used in a golf course where use of metal spikes is prohibited.

[0002]

2. Description of the Related Art Conventional spike-replaceable golf shoes have a structure in which a metal spike having a pointed steel spike at the center of a metal or plastic circular flange is detachably screwed. Was common. However, in recent years, the use of metal spikes on golf courses has been banned because of damage to the lawn.

Therefore, instead of mounting metal spikes, golf shoes have been used in which a resin spike having ribs formed on the surface of a plastic circular flange is screwed. However, in a golf shoe in which a metal spike is simply replaced with a resin spike, a load is concentrated on the resin spike, and the lawn is rather damaged.

In order to solve this problem, a resin spiked golf shoe as shown in FIG. 4 has an auxiliary projection formed at a portion other than the resin spike mounting portion of the sole and has a gripping property while distributing a load. It has come to be used.

[0005]

As a result, resin spiked golf shoes have been sold, but those who have only conventional spike-replaceable golf shoes play on golf courses where metal spikes are prohibited. Therefore, it was necessary to purchase resin spike golf shoes newly.

[0006] However, there is an increasing number of accidents in which only the resin spike is purchased and the lawn is damaged by playing simply by replacing the metal spike of the conventional spike-replaceable golf shoe with the resin spike. This is because, as shown in FIG. 3A, the load is concentrated on the resin spike portion, and the lawn surface is depressed in the shape of the flange, thereby damaging the lawn. Further, in such a method of use, the load is concentrated on the resin spike portion, the wear of the rib of the resin spike is accelerated, the grip performance is reduced, and there is a possibility that the play may be adversely affected.

[0007] Therefore, it has been desired to develop a component that can be attached to the sole of a spike-replaceable golf shoe to be a sole similar to the sole of a resin spike golf shoe.

[0008]

According to the present invention, two or four adjacent spikes which are screwed to the sole of a spike-replaceable golf shoe are tightly fitted between the flange and the sole bottom,
A detachable plate formed to be mounted inside the outer periphery of the sole, wherein a spike auxiliary projection is formed on the ground surface side other than the through hole of the spike mounting screw and the flange contact portion on the plate base. A plate with a spike assisting projection for a golf shoe is attached to the forefoot portion and the heel portion of the sole.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A spike auxiliary projection plate for a golf shoe according to the present invention is narrowly fitted between a flange of a spike screwed to a sole of a spike-replaceable golf shoe and a sole bottom surface, and an outer periphery of the sole. A detachable plate formed so as to be mounted on the inner side, wherein a spike assisting projection is formed on the ground surface side other than the through hole of the screw for attaching the spike and the flange contact portion on the plate base. .

Further, the plate with spike assisting projections for golf shoes can be formed as a single plate as a whole sole or as two plates of a forefoot part and a heel part of the sole. The triangular, square or elliptical shape, which is screwed with two or four spikes, is more flexible because it can be replaced when it is partially damaged or used for multiple shoes. good.

Further, the plate with a spike assisting projection for a golf shoe mounted on the forefoot portion does not overlap the bending line of the base joint of the toe and the bending line of the metatarsal front joint so as not to impair the flexibility of the shoe. It is desirable to form it. Therefore, since the spikes of the spike replacement golf shoes are generally seven or six at the forefoot, they are screwed by three or two spikes at the toe, and are triangular or oval. A plate with a spike auxiliary projection for a golf shoe, a plate with a spike auxiliary projection for an elliptical golf shoe which is screwed by two spikes following the left and right, and a screw with two spikes following the ellipse It is preferable that the plate is formed as three plates of an elliptical plate with spike auxiliary projections for golf shoes.

The spike-assisting projection plate for a golf shoe mounted on the heel portion is generally four spikes on the heel portion of a spike-replaceable golf shoe.
From the viewpoint of the above-mentioned flexibility, it is preferable to form two oblong plates with spike auxiliary projections for golf shoes that are screwed together with two adjacent spikes.

[0013] The spike assisting protrusion is higher than the height of the spike on which the golf shoe spike assisting protrusion-provided plate is screwed so that the spike function is not impaired when the golf shoe spike assisting protrusion-fitting plate is screwed by the spike. It is formed to be lower. In addition, if the difference between the height of the spike screwed to the spike auxiliary projection plate for golf shoes and the height of the spike auxiliary projection is increased, the grip performance increases, and if the difference is reduced,
If you prepare a plate with spike auxiliary projections for golf shoes with different heights of spike auxiliary projections, you can change the gripping property, depending on the length of the lawn, the hard and soft lawn You can use them properly.

The spike assisting projections are formed into various shapes such as frustum, column or pyramid, and cone. When hitting a golf ball, there is a movement in which the foot tilts left and right,
At this time, it is desirable to form the spike assisting protrusion near the outer periphery of the sole into a triangular pyramid, a quadrangular pyramid, a cone, or the like so as to prevent slipping.

The through holes for the spike mounting screws in the triangular-shaped golf shoe spike-assisting projection plate and the square-shaped golf shoe spike-assisting projection plate are opened near the tops of the triangular and square shapes. In the elliptical plate with spike assisting projections for golf shoes, holes are formed near both ends of the elliptical shape. The larger the diameter of the through hole is, the more it can be used for a plurality of shoes and sizes and the flexibility is good. However, in order for the through hole to be hidden by the flange and to be firmly fixed, the radius of the flange is preferably about the same.

The material used for the spike assisting projection plate for golf shoes is nylon, which is an elastic synthetic resin.
Urethane, PVC, synthetic rubber or their foams are used. In addition, when the plate base of the plate with spike auxiliary projections for golf shoes is integrally formed with nylon or urethane and the spike auxiliary projections with synthetic rubber, both wear resistance and weight reduction can be achieved.

Further, the hardness of the spike assisting projection is determined according to JIS.
When the A hardness is 85 to 95, the gripping property is increased, and when the A hardness is 75 to 85, the lawn can be hardly damaged.

The spike for mounting the plate with a spike assisting projection for a golf shoe may be a metal spike or a resin spike as long as the spike assisting projection can be screwed without contacting the flange.
