Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to spikes for golf shoes that use pins made of zirconia and have excellent wear resistance and durability.

(Prior Art) Conventionally, spikes for golf shoes (hereinafter simply referred to as spikes) have been used, which are made by integrating a zirconia pin with a substantially conical leg protruding from the seat and attached to a metal washer. has been done.

However, when the pin is directly attached to the washer by brazing, the strength tends to deteriorate because zirconia has a transformation point around 500°C.

Furthermore, when attaching a pin to a washer by caulking a portion of the washer, the caulking operation damages the pin and causes the leg portion of the pin to easily break.

Thus, conventionally, it has not been possible to fully utilize the wear resistance and durability of zirconia pins.

(Problems to be Solved by the Invention) The object of the present invention is to provide spikes for golf shoes that have pins made of zirconia and exhibit sufficient wear resistance and durability.

(Means for solving the problems) The spike for golf shoes according to the present invention has the following configuration.

A storage section 2 is formed by recessing the center of the back surface of the large-diameter dish-shaped part 1, and an insertion hole 3 is bored in the center of the storage part 2. A washer a with a small hole 5 drilled therein, a male screw part 7 protruding from the center of a base plate part 6 having a larger diameter than the storage part 2 of the washer a, and a base plate part at a position corresponding to the small hole 5 of the washer a. 6, a screw body b with a notch 8
and a pin p made of zirconia having a substantially conical leg portion 11 projecting from the seat portion 12.

Then, the leg part 11 of the pin p is inserted into the insertion hole 3 of the washer a, and the pin p stored in the storage part 2 of the washer a is
With the seat part 12 of the screw body b covered with the base plate part 6 of the screw body b, the periphery of the base plate part 6 is spot welded 13 or brazed to the dish-shaped part 1 of the washer a at a plurality of places, and the washer a and the screw Body b and pin p are integrated.

(Example) As shown in FIGS. 1 and 2, the spikes for golf shoes according to the present invention are made of zirconia pins p.
Store the seat part 12 of the washer a in the storage part 2 of the washer a, and
Insert the leg portion 11 of the washer a into the insertion hole 3 of the washer a, and with this seat portion 12 covered with the base plate portion 6 of the screw body b, insert the peripheral edge of the base portion 6 of the screw body b into the dish-shaped portion 1 of the washer a. The washer a, the screw body b, and the pin p are integrated.

The washer a is made of metal such as iron, stainless steel, or hardened steel, and as shown in FIG. An insertion hole 3 is made in the center of the part 2, a shoulder part 4 is formed around the insertion hole 3, and two small holes 5 are made in the dish-shaped part 1 around the storage part 2. It is.

The screw body b is made of metal such as iron, stainless steel, or hardened steel, and as shown in FIG.
A male screw portion 7 is located in the center of the larger diameter, disk-shaped base portion 6.
A notch 8 is provided in the base plate 6 at a position corresponding to the small hole 5 of the washer a.

The pin p is made of zirconia, and as shown in FIG. , which protrudes from the seat portion 12 having approximately the same diameter as the inner diameter of the storage portion 2 of the seat plate.

The zirconia that is the raw material for the pin P is not particularly limited, but it is preferably one whose main material is zirconium oxide containing 3 to 20 mol % of yttrium oxide.

Next, a method of attaching the zirconia pin p to the washer a and the screw body b will be explained.

Pre-made zirconia pin p seat 12
is stored in the storage part 2 of washer a, and the leg part 11 of pin p is
into the insertion hole 3 of washer a.

Then, the seat part 12 of this pin p is covered with the base plate part 6 of the screw body b, and with the small hole 5 of the seat plate and the notch part 8 of the screw body b overlapped, the base part 6 of the screw body b is attached to the washer. It was placed in the center of the back surface of the dish-shaped part 1 of the washer a, and the periphery of the base plate part 6 of the screw body b was spot-welded 13 to the dish-shaped part 1 of the washer a at multiple locations, as shown in FIGS. 1 and 2. As shown in the figure, the washer a, the screw body b, and the pin p are integrated.

This spike is then used by inserting the protrusion of the spike attachment fitting into the small hole 5 of the washer a, turning it, and screwing it into the sole of the shoe, like a normal spike.

Here, since the small hole 5 of the seat plate and the notch 8 of the screw body b overlap, when screwing the spike, not only the washer a but also the screw body b must be turned at the same time with the spike mounting bracket. Therefore, the spike can be securely screwed onto the sole of the shoe without applying unnecessary force to the spot weld 13.

The seat part 12 of the pin p, which has a slightly larger diameter than the base of the leg part 11, is attached to the storage part 2 of the washer a having the large diameter dish-shaped part 1, and this seat part 12 is attached to the base part 6 of the screw body b.
Since the peripheral edge of the base plate part 6 is fixed to the dish-shaped part 1 of the washer a in a state where the base plate part 6 is covered with These golf shoes have excellent walking performance with no feeling of pushing up when in use.

In addition, in the above embodiment, with the small hole 5 of the washer a made in advance and the notch 8 of the screw body b overlapped,
The explanation has been given using an example in which the base plate part 6 of the screw body b is welded to the dish-shaped part 1 of the washer a. Two small holes 5 may be formed in the dish-shaped portion 1 around the portion 2, and at the same time, a notch portion 8 may be formed in the base portion 6 of the screw body b.

In the embodiment, the base plate 6 of the screw body b is connected to the washer a.
The explanation was given using the example of spot welding the dish-shaped part 1 of
The base plate portion 6 of the screw body b may be fixed to the dish-shaped portion 1 of the washer a by brazing.

In the embodiment described above, the substantially conical leg portion 11 is attached to the seat portion 1.
Although the pin p is provided as an example of protruding from the seat portion 12, the pin p may be provided with a mold hole provided in the center of the upper surface of the seat portion 12.

In the above embodiment, an example was explained in which the spike can be screwed onto the sole of a shoe by applying a regular spike attachment fitting to the small hole 5 of the washer a and the notch 8 of the screw body b and turning it. The circumferential edge of the dish-shaped portion 1 of the washer a may be cut out at a plurality of locations, or the storage portion 2 of the washer a may be made square so that the spike can be screwed onto the sole of the shoe.

(Operations and Effects of the Invention) The golf shoe spike according to the invention has the above-mentioned structure, and the leg part 11 of the pin p is inserted into the insertion hole 3 of the washer a, and the pin is housed in the storage part 2 of the washer a. p
The seat portion 12 of the screw body b is covered with the base plate portion 6 of the screw body b, and the peripheral edge of the base plate portion 6 is fixed to the dish-shaped portion 1 of the washer a. Through the integration work, the pin P will not deteriorate in strength or be damaged, and the wear resistance and durability of the zirconia pin P can be fully demonstrated, resulting in excellent durability. It is something that

The spike for golf shoes according to the present invention has the above-mentioned configuration, and the pin p stored in the storage part 2 of the washer a.
The seat portion 12 of the screw body b is covered with the base plate portion 6 of the screw body b, and the peripheral edge of the base plate portion 6 is fixed to the dish-shaped portion 1 of the washer a, so that the washer a, the screw body b, and the pin p are It can be easily and firmly integrated.

The spike for golf shoes according to the present invention has the above-mentioned configuration, and the pin p stored in the storage part 2 of the washer a.
