Description

[Detailed explanation of the idea] The present invention relates to spikes for golf shoes.

Conventionally, the shank of golf shoe spikes,
The main body of the golf shoe's spike, which consists of a flange part and a threaded part, was made of steel.

As a result, the weight became large, and even if the weight could be reduced to a certain extent, there was a certain limit. Moreover, as shown in FIG. 3, conventionally, after once the spike body 4' consisting of the shank 1', flange part 2', and threaded part 3' is molded,
Since two steps were required to press the cemented carbide chip 5' in the direction of the arrow, there was a problem in that the machining process was time-consuming.

This idea was created in view of these points.
The gist of this is that the spike body of golf shoes consists of a shank, a flange part, and a threaded part, and a cemented carbide chip embedded in the tip of the shank in a slightly protruding manner. In the spike, the spike body is integrally formed of synthetic resin, and the tip is formed in a tapered shape that tapers toward the protruding tip, and the shank of the tip A spike for golf shoes characterized in that the embedding into the body is performed simultaneously when the body is formed by injection molding by positioning the chip at a required location in a mold for molding the body, and the purpose thereof is to This makes it possible to reduce the weight to approximately 1/7 to 1/8 of the weight of conventional spikes, thereby providing comfortable golf shoes that are easy to walk in and reduce fatigue. Located in
In addition, the spikes can be molded in one step by injecting synthetic resin with the chip set in a mold and molding them in one piece, so they are inexpensive, easy to supply to the market, and the base of the chip is To provide a spike for golf shoes that is fixedly held in a shank and does not fall out unexpectedly because it is formed in a tapered shape having the largest diameter and tapering toward the protruding tip.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view of a mid-longitudinal cross-section of a spike for golf shoes in which the present invention is implemented, and FIG. The main body 4 is shown, 5 is a cemented carbide chip embedded in the tip 6 of the shank 1 in a slightly protruding manner, and 7 is the sole of the golf shoes.

The present invention provides the above-mentioned chip 5 in these structures.
is formed so as to become gradually tapered from the base 8 to the protruding tip 9, and is embedded and fixed in the shank 1 of the spike body 4 made of synthetic resin.

That is, the chip 5 is positioned at the required location of the injection mold, and the synthetic resin for injection molding is injected into the mold to form the spike body 4, and at the same time, the chip 5 is embedded into the shank 1. It can be done. In this case, since the tip 5 has a tapered shape with a larger diameter at the root 8, it is firmly held within the shank 1 and does not fall out unexpectedly.

In this way, the golf shoe spike of the present invention is formed by forming the tip 5 with a larger diameter at the base 8 and gradually tapering toward the protruding tip 9. The formed tip 5 is positioned in a mold so that it is held in the shank 1, and synthetic resin is injected.The shank 1, flange part 2, and threaded part 3 are integrally formed to form the spike, so it is made of steel. The weight can be reduced to approximately 1/7 to 1/8 compared to the spike itself. In other words, by making it possible to reduce the weight, it becomes more comfortable to wear, making it easier to walk and reduces fatigue.Also, since the spike body is made of synthetic resin, the material is inexpensive, and it can be molded in one step using injection molding. It has the advantage of being inexpensive and easy to supply on the market, and the shape of the tip is tapered toward the protruding tip, so it does not hold firmly in the shank. , it is possible to provide spikes that are fixed and protected and will not fall off accidentally.
