DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spike for a golf shoe having a disk with a projection having a depression formed on the lower surface, and a bolt for attaching the shank portion to the golf shoe by penetrating the disk from the depression.

[0002]

2. Description of the Related Art A conventional golf shoe spike structure is shown in FIG.
As shown in FIG. 5, the disk 50 has a plurality of protrusions 51 projecting from the lower surface and a threaded shank 52 projecting from the upper surface of the disk, and two openings 53 are formed in the lower surface of the disk 50. These two openings 53
The detachable tool 54 can be engaged with the disc 50 by inserting two engaging projections 55 of the detachable tool into the disk 50. By rotating the detachable tool 54 together with the disc 50, the threaded shank 52 can be connected to the sole of the golf shoe. Into the screw hole 56. The disk 50 and the projection 51 are made of a plastic material.
Is slightly flexible so that the person wearing the shoe feels comfortable. The threaded shank 52 has a screw hole 5
6 must be formed of metal so as to be securely screwed. The metal threaded shank 52 bonds to the disk 50 during plastic injection molding of the disk 50.

[0003]

However, it is difficult to accurately position the threaded shank 52 on the disk 50 by this method. That is, a shank 5 with a thread during molding
2 easily tilts with respect to the disk 50, and the defect occurrence rate of the product increases.

Accordingly, it is an object of the present invention to overcome the disadvantages of the conventional spike structure and to provide a spike for a golf shoe that is simple to manufacture and assemble.

In order to achieve this object, a spike of a golf shoe according to the present invention is a plate having a plurality of projections projecting from a lower surface and a central through hole, wherein a depression is formed in the lower surface of the plate to define the depression. A plate provided with a plurality of projections projecting radially inward from the periphery of the recess, a head, and a threaded shank projecting from the head.The threaded shank is inserted into the center through hole of the plate. A bolt having a plurality of notches formed on a peripheral edge of the head, the plurality of notches capable of being fitted with the protrusions, and the number of the notches being provided on the plate. At least two more than the number of
At least two notches are provided on the periphery of the depression that defines the depression, the head of the bolt is housed in the depression of the plate, and when the projection is fitted to the notch, a notch that does not fit to the projection. The notch in the depression of the plate is aligned to form at least two openings so that a detachable tool can be inserted.

According to the present invention, this two-part configuration simplifies the manufacture and assembly of spikes for golf shoes,
The occurrence rate of product defects can be reduced, and a wide variety of products can be finished.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be described with reference to the drawings.

Referring to FIGS. 2-4, the spike of a golf shoe according to the present invention has a plurality of projections 12 projecting from the lower surface and a plate or disk 11 provided with a central through hole 14. FIG. A depression 13 is formed on the lower surface of the disk 11, and a plurality of protrusions 15 are provided which project radially inward from the periphery of the depression defining the depression 13 communicating with the center through hole. The bolt 17 is a head 171 and the head 1
The threaded shank 170 projects from the center through hole 1 of the disk 11.
4 so that the head 171 is accommodated in the recess 13. A plurality of notches 18 are provided on the periphery of the head 171 so that the protrusions 15 of the disk fit. At least two semi-circular notches 16 are provided around the periphery of the depression defining the depression 13.
And the head 171 has at least two at the periphery of the head.
Are provided, and the head 171 is recessed 13
When the projection 15 is fitted in the notch 18, the at least two semicircular notches 16
The semicircular notches 19 each define at least two openings 100.

When attaching a spike to the sole 20 of a golf shoe, the protrusion 55 of the tool 54 shown in FIG. 1 is inserted into the two openings 100 of the spike and a threaded shank 170 is provided.
Is screwed into the screw hole 21. As the protrusion 15 of the disc fits into the notch 18 in the head 171 of the bolt 17, the disc 11 and the bolt 17 rotate together and align with the sole 20 of the golf shoe.

The disc 11 can be easily replaced in the event of breakage or wear, and this replacement can be performed in a short time by the user of the shoe. The disk 11 and the bolt 17 are manufactured separately. Therefore, an appropriate material can be selected according to actual needs.

The above description is only for the explanation of the embodiment of the present invention, and it is needless to say that arbitrary changes and modifications can be made within the scope of the claims.
