Description

Golf shoe spike structure with deformation effect

The present invention is related to a shoe spike structure, and in particular to a shoe spike structure of golf shoes with a deformable effect.

Golf is a recreational and competitive sporting activity that mainly involves hitting the ball into a distant hole, so golf courses are usually outdoors. In order to increase the difficulty, golf courses are designed with different terrains and venues of different properties (such as sand pits, grass areas, rough areas, etc.). Since it is best for the player to stand steadily on the course when hitting the ball, the soles of general golf shoes are equipped with spikes to provide better friction. For example, the patent application No. 099211622 of the Republic of China provides a "shoe body structure with spikes". In order to achieve a better grip effect, the patent case usually designs the shoe spikes into a ring-shaped multi-nail claw structure, and each shoe spike is made of a wear-resistant and high-hardness material to have sufficient strength and wear resistance.

However, since the shoe spikes of the patent prior art can achieve sufficient grip when used in the sand trap area by using a high-hardness material setting, when used in the grass area, the high-hardness nail claw structure is deeply pierced into the soil under the grass to generate good grip or bite force. In this way, a small piece of grass will be dug and damaged by the shoe spikes at the moment of hitting the ball.

The purpose of the present invention is to provide a golf shoe spike structure with a deformable effect, which can maintain appropriate grip without excessive force to damage the turf when used on a field without small stones, and provide higher grip when used on a field with small stones.

To achieve the above-mentioned purpose, the present invention is a shoe spike structure of a golf shoe with a deformable effect, which is suitable for being arranged on a sole, and the sole has a coupling column portion facing downward. The shoe spike structure of the golf shoe with a deformable effect comprises: a shoe spike plate body, which is a thermoplastic polyurethane (TPU) material, and has a plate body ring portion arranged on the coupling column portion, and an inner ring edge connected to the plate body ring portion and abutting against the coupling column portion. A pressure-bearing portion under the combined column portion, the pressure-bearing portion can move between a normal position and a pressure-bearing position deformed by pressure toward the sole; and a plurality of nail claws, which are made of thermoplastic polyurethane (TPU) material and are radially arranged on the disk ring of the shoe nail disk and extend outward and downward, each of the nail claws having a connecting portion connected to the outer ring edge of the disk ring, and a claw portion connected to the connecting portion.

The effect of the present invention is that: through the structural design of the shoe nail plate, each nail claw is linked or unlinked with the different positions of the pressure-bearing part of the shoe nail plate, that is, when the present invention is used in a venue with small stones, such as a sand pit area, a grass area with small stones, and a long grass area with small stones, the pressure-bearing part of the shoe nail plate will contact the small stones, and then the pressure-bearing part is squeezed by the small stones and deformed toward the sole, and the deformed pressure-bearing part causes the ring part of the plate and each nail claw to be deformed synchronously, and causes the claw part of each nail claw to shrink and deform inward synchronously, so as to provide a better gripping effect and effectively prevent slipping. When the present invention is used on a field without pebbles, such as a ridge or a grass field without pebbles, the pressure-bearing portion of the shoe nail plate is not under pressure, and the pressure-bearing portion of the shoe nail plate is in a normal position, so that the claws of each nail claw return to their original state, and when the claws of each nail claw come into contact with the field without pebbles, the claws of each nail claw expand outward, maintaining appropriate grip without excessive force to damage the grass.

Preferably, when the pressure-bearing portion of the shoe nail plate is in a normal position and the claw portion of each nail claw is squeezed by an upward external force, the claw portion of each nail claw expands outward.

Preferably, the pressure-bearing portion of the shoe stud plate can automatically return to a normal position from a pressure-bearing position.

Preferably, the coupling column portion of the sole has an annular side surface and a bottom surface, the disc annular portion is arranged on the annular side surface of the coupling column portion, and the pressure-bearing portion is arranged on the bottom surface of the coupling column portion.

Preferably, the shoe spike plate body also has a coupling ring portion disposed on the inner ring edge of the plate body ring portion and located above the pressure-bearing portion, and a coupling groove for partially inserting the coupling column portion is formed between the coupling ring portion and the pressure-bearing portion, and the coupling ring portion is disposed on the side surface of the coupling column portion of the sole.

Preferably, the pressure-bearing portion of the shoe stud plate has a plurality of ribs radiating outward from the center.
