Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf shoe in which a plurality of elastic projections for preventing slippage are formed on the sole of the sole, projecting downward from the base of the sole, and having a ground contact surface at the tip thereof in contact with the ground.

[0002]

2. Description of the Related Art Spike type and spikeless type golf shoes are widely known and put to practical use as golf shoes worn during golf play. A spike-type golf shoe has a plurality of conical or frusto-conical metal spikes attached to a shoe sole for slip prevention. Spikeless type golf shoes
Again, for the purpose of slip prevention, a plurality of columnar, frustoconical, etc. elastic projections (rubber studs) are provided on the sole of the shoe, projecting downward from the base of the sole, and having a ground contact surface at the tip that comes into contact with the ground. The elastic projection is usually formed integrally with the base of the shoe sole by projecting a part of the base of the shoe sole.

[0003] Of the above-mentioned golf shoes of each type,
The spike type uses metal spikes, which are hard materials, as anti-slip projections, so it has good grip on the grass surface, and is therefore most suitable for playing and walking in each hole. On the other hand, when walking on a hard surface such as a pavement road in a course or a floor of a clubhouse, there is a drawback that it is difficult to walk due to pushing up by a metal spike and is easily tired.

[0004] On the other hand, the spike-less type has good elasticity because the elastic projections are rich in flexibility, so that there is no problem caused by pushing up as in the above-mentioned spike-type golf shoes, and walking is good.

[0005]

However, golf shoes of the spikeless type have good walking characteristics because the elastic projections are rich in flexibility as described above, but because the elastic projections do not penetrate the grass surface sufficiently. In some cases, the grip on the ground may be insufficient. Therefore, in particular, when performing a swing at a tee ground, a fairway, or the like, there is a case where the lack of the grip performance becomes a problem.

The present invention has been made in view of the above circumstances, and is a golf shoe having an elastic projection provided on a shoe sole.
It is an object of the present invention to provide a golf shoe with improved grip on the ground during a swing.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a golf shoe in which a plurality of elastic projections projecting downward from a base of the shoe sole and having a ground contact surface at the tip end contacting the ground are formed on the shoe sole. A part or all of the grounding surface of the elastic projections present in the outer area of the shoe sole, and an inclined surface inclined in a direction to decrease the height of the elastic projections from the inside to the outside in the width direction of the shoe sole. The present invention provides a golf shoe characterized in that:

As shown in FIG. 1, a golf shoe according to the present invention has a plurality of elastic projections 8 (in the drawing, one having a ground contact surface 6 projecting downward from a base 4 of a sole 2 and having a contact surface with the ground).
Are shown on the sole 2. Then, a part or all of the grounding surface 6 of the elastic projections 8 present in the outer area of the shoe sole 2 is inclined such that the height of the elastic projections 8 is reduced from the inside to the outside in the width direction of the shoe sole 2. There is as a face.

Here, the outer area of the shoe sole is a straight line connecting the innermost point of the tread portion of the shoe sole and the innermost point of the heel part, as will be described with reference to the drawings in an embodiment described later. When the angle between the inner edge straight line and the outer edge straight line at the intersection of the (inner edge straight line) and the straight line (outer edge straight line) connecting the outermost point of the tread portion and the outermost point of the heel portion is α, the outer edge straight line And a straight line (section line) which passes through the intersection and lies inside the outer edge straight line and has an angle β of 1/3 of the angle α with the outer edge straight line, and is simply referred to as an area. And substantially 1/3 of the outside of the shoe sole in the width direction.

[0010] From the downswing to the finish of the golf swing, the right-handed player concentrates his weight on the outside area of the sole of the left footed shoe, and the left-handed player concentrates his weight on the area outside the sole of the right footed shoe, and the sole is inclined and the sole is inclined. The area inside in the width direction from the outside area is floated from the ground. The golf shoe of the present invention has an elasticity in which an outer surface of the sole where weight is concentrated during a swing has an inclined surface inclined in a direction in which the height of the elastic protrusion decreases from the inner side to the outer side in the width direction of the sole. Since the projection (hereinafter, this projection may also be referred to as an inclined projection) is provided, the contact surface of the inclined protrusion is substantially horizontal, almost the entire contact surface comes into contact with the ground, and the contact surface is pressed by a large pressure. Pressed to the ground. Therefore, in the golf shoe of the present invention, the grip on the ground during a swing is improved.

Hereinafter, the present invention will be described in more detail. In the golf shoes of the present invention, the material of the sole is not particularly limited, but rubbers, foamed rubbers, plastics, foamed plastics, and more specifically, butadiene rubber, polyurethane, thermoplastic polyurethane, foamed urethane, EVA (ethylene vinyl acetate), synthetic rubber, or the like can be used. The shoe sole may have a single-layer structure or a multilayer structure.

In the present invention, a plurality of elastic projections projecting downward from the base of the shoe sole and having a ground contact surface at the tip thereof in contact with the ground are formed on the shoe sole. In this case, the elastic projection is usually formed integrally with the base of the shoe sole, but may be fixed to the base of the shoe sole. In addition, small unevenness may be provided on the ground surface of the elastic projection to prevent slippage.

The shape of the elastic projection can be any shape. For example, as shown in an embodiment described later, a gourd-shaped elastic projection, arrow blade-shaped elastic projection, circular elastic projection, shoulder boards Shaped elastic protrusions, polygonal elastic protrusions, and the like can be used, but are not limited thereto.

Although the size of the elastic projection can be appropriately selected, referring to FIG. 1, the maximum width m and the maximum length n at the base of the elastic projection (joint to the base of the shoe sole) are 3 respectively. It is suitable that the height is 15 mm, especially 5 to 10 mm, and the maximum height h is 3 to 6 mm. Also, the elastic projection is preferably formed in a tapered shape in which the width and the length decrease as going from the root to the distal end as in the example of FIG. 1, but the present invention is not limited to this. May be substantially equal to the width and length at the tip.

According to the present invention, a part or the whole of the contact surface of the elastic protrusion existing in the outer area of the shoe sole is inclined so as to decrease the height of the elastic protrusion from the inside to the outside in the width direction of the shoe sole. Face. In this case, the angle θ between the inclined surface and the horizontal plane is preferably 5 to 20 °, particularly preferably 7 to 13 °. If the angle θ is smaller than 5 ° or larger than 20 °, the effect of the present invention of improving grip on the ground may not be sufficiently obtained. The angle θ refers to the inclination angle from the inside to the outside in the width direction of the shoe sole, regardless of the orientation of the elastic projection with respect to the shoe sole in plan view.

In the present invention, the elastic projection present in the outer area of the shoe sole means an elastic projection entirely included in the outer area. Therefore, in the present invention, the inclined surface may be a part or the whole of the elastic projection entirely included in the outer area, and a part is included in the outer area, and the remaining part is in the area inside the outer area. When the elastic projection is included, the ground surface of the elastic projection may be the inclined surface or the horizontal surface.

In the present invention, all of the elastic projections included in the outer area may be inclined projections, or some of them may be inclined projections. In the latter case, for example, an inclined projection and a non-inclined projection (a normal elastic projection having a horizontal grounding surface) are alternately arranged from the toe to the heel, or a tread portion where the weight is more concentrated during a swing. And place the inclined projection on the heel,
Non-inclined projections can be arranged on the toe and arch.

It should be noted that there is no particular problem even if the inclined projections are arranged in an area other than the outer area of the shoe sole. Also, as described above, the right-handed player swings his left foot when swinging,
The left-handed player concentrates his weight on the outer area of the sole of the right foot shoe, but if the inclined projections are arranged on the outer area of the sole of the right foot shoe and the left foot shoe, the golf of the present invention can be used. Shoes can be used by both right-handed and left-handed players. Further, in the golf shoe of the present invention, other protrusions such as metal spikes can be provided on the shoe sole in addition to the elastic protrusions as long as the effect of the inclined protrusions is not impaired.
