Description

Technical Field

[0001] The present invention relates to a shoe spike structure, and in particular to a shoe spike structure of a golf shoe with a deformation effect. Background Art

[0002] Golf is a recreational and competitive sporting activity, which mainly involves hitting the ball into a distant hole, so golf courses are usually outdoors. In order to increase its difficulty, different terrains and venues of different properties are designed on the golf course (such as sand trap areas, grass areas, long rough areas, etc.). Because it is best for the hitter to stand stably on the golf course when hitting the ball, general golf shoes are equipped with spikes on the soles to provide better friction. For example, Taiwan, China application No. 099211622 provides a patent case for a "shoe body structure with spikes." In order to achieve a better grip effect, the patent case usually designs the spikes into a ring-shaped multi-nail claw structure, and each spike is made of a wear-resistant and high-hardness material to have sufficient strength and wear resistance.

[0003] However, since the spikes of the prior patent can achieve sufficient grip when used in a sand pit area through the high-hardness material setting, when used in a grass area, the high-hardness spike claw structure penetrates deep into the soil under the grass to generate good grip or bite force. As a result, a small piece of grass will be dug out and damaged by the spikes at the moment of applying force when hitting the ball. Summary of the invention

[0004] The purpose of the present invention is to provide a golf shoe spike structure with a deformation effect, which can maintain appropriate grip without excessive force to damage the grass when used on a field without small stones, and provide higher grip when used on a field with small stones.

[0005] To achieve the aforementioned purpose, the present invention is a spike structure of a golf shoe with a deformation effect, which is suitable for being arranged on a sole having a coupling column portion facing downward. The spike structure of the golf shoe with a deformation effect comprises: a spike disc body, which is made of thermoplastic polyurethane (TPU) and has a disc body ring portion arranged on the coupling column portion, and a pressure-bearing portion connected to the inner ring edge of the disc body ring portion and abutted against the lower part of the coupling column portion, the pressure-bearing portion can move between a normal position and a pressure-bearing position in which it is compressed and deformed toward the sole; and a plurality of spike claws, which are made of thermoplastic polyurethane (TPU) and are radially arranged on the disc body ring portion of the spike disc body and extend outward and downward, each of the spike claws having a connecting portion connected to the outer ring edge of the disc body ring portion, and a claw portion connected to the connecting portion.

[0006] The effect of the present invention lies in that: through the structural design of the spike plate body, each spike claw is linked or unlinked depending on the position of the pressure-bearing part of the spike plate body. 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, or a long grass area with small stones, the pressure-bearing part of the spike plate body will contact the small stones, and then the pressure-bearing part will be squeezed by the small stones and deformed toward the sole, and the deformed pressure-bearing part will cause the ring part of the plate body and each spike claw to deform synchronously, and cause the claw part of each spike claw to shrink and deform inward synchronously, thereby providing a better gripping effect and effectively preventing slipping. When the present invention is used on a field without small stones, such as a ridge or a grassy field without small stones, the pressure-bearing portion of the spike plate is not compressed, and the pressure-bearing portion of the spike plate is in a normal position, so that the claws of each spike claw are restored to their original state, and when the claws of each spike claw contact the field without small stones, the claws of each spike claw expand outward, maintaining appropriate grip without excessive force to damage the grass.

[0007] Preferably, when the pressure-bearing portion of the shoe spike plate body is in a normal position and the claw portion of each spike claw is squeezed by an upward external force, the claw portion of each spike claw expands outward.

[0008] Preferably, the pressed portion of the spike plate can automatically return to a normal position from a pressed position.

[0009] Preferably, the coupling column portion of the sole has a ring side surface and a bottom surface, the disc ring portion is arranged on the ring side surface of the coupling column portion, and the pressure-bearing portion is arranged on the bottom surface of the coupling column portion.

[0010] Preferably, the spike plate body further comprises a coupling ring portion which is arranged 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 arranged on the ring side surface of the coupling column portion of the sole.

[0011] Preferably, the pressure-bearing portion of the spike plate has a plurality of ribs radiating outward from the center. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] See also Figure 1A to Figure 2 As shown, the spike structure of golf shoes with deformation effect provided by the embodiment of the present invention is suitable for being arranged on a sole 10, the sole 10 has a downwardly facing coupling column 11, and the sole 10 is made of TPE or EVA material, but not limited thereto. In this embodiment, the spike 100 structure is integrally formed with the sole 10, so that the spike 100 will not fall off the sole 10, but not limited thereto. Figure 2 Only a part of the sole 10 structure is shown, and only one connecting column 11 is used for illustration. The connecting column 11 of the sole 10 has a ring side surface 111 and a bottom surface 112. The spike structure of the golf shoe with deformation effect is mainly composed of a spike plate 20 and nine spike claws 30, wherein:

[0023] The shoe spike plate 20 is made of thermoplastic polyurethane (TPU) and has a plate ring portion 21 disposed on the coupling column portion 11, and a pressure receiving portion 22 connected to the inner ring edge 211 of the plate ring portion 21 and abutting against the lower portion of the coupling column portion 11. The pressure receiving portion 22 can be in a normal position (such as Figure 1B ) and a compressed position (such as Figure 3B and Figure 4 ) between; In this embodiment, the hardness of the shoe spike disc 20 is harder than the hardness of the sole 10, but not limited to this, the disc ring portion 21 is provided on the ring side surface 111 of the combined column portion 11, the pressure-receiving portion 22 is protruded downward from the inner ring edge 211 of the disc ring portion 21 and is provided on the bottom surface 112 of the combined column portion 11, and the pressure-receiving portion 22 has a plurality of ribs 221 radiating outward from the center; In addition, refer to Figure 1A and Figure 2 As shown, the spike plate body 20 also has a coupling ring portion 23 disposed on the inner ring edge 211 of the plate body ring portion 21 and located above the pressure receiving portion 22, and a coupling groove 24 for the coupling column portion 11 to be partially placed is formed between the coupling ring portion 23 and the pressure receiving portion 22, and the coupling ring portion 23 is disposed on the ring side surface 111 of the coupling column portion 11 of the sole 10. At the same time, when the external force is eliminated, the pressure receiving portion 22 of the spike plate body 20 can be moved from the pressure position ( Figure 3B ) automatically returns to its normal position ( Figure 1B ).

[0024] Each of the spike claws 30 is made of thermoplastic polyurethane (TPU) and is radially arranged on the ring portion 21 of the shoe spike plate 20 and extends outward and downward. Each of the spike claws 30 has a connecting portion 31 connected to the outer ring edge 212 of the ring portion 21, and a claw portion 32 connected to the connecting portion 31. In this embodiment, each of the spike claws 30 and the shoe spike plate 20 are integrally formed and made of the same material, but the present invention is not limited thereto.

[0025] Thus, when the pressure receiving portion 22 of the shoe spike plate 20 is in the pressure receiving position (such as Figure 3A , Figure 3B and Figure 4 ), each of the nail claws 30 will be deformed synchronously due to the compression deformation of the pressure-bearing portion 22 toward the sole 10, and the claw portion 32 of each nail claw 30 will shrink inward. Figure 1A , Figure 1B and Figure 2 ), the claw portion 32 of each spike claw 30 returns to its original state. When the pressure receiving portion 22 of the spike plate body 20 is in the normal position and the claw portion 32 of each spike claw 30 is pressed upward by an external force (such as Figure 5A , Figure 5B and Figure 6 ), the claw portion 32 of each nail claw 30 expands outward.

[0026] The above is a description of the main components of the embodiment of the present invention. The operation mode and effect of the present invention are described as follows:

[0027] See also Figure 3A , Figure 3B and Figure 4As shown, when the present invention is used in a venue 90 with small stones 91, such as a sand pit area, a grass area with small stones, or a long grass area with small stones, the pressure-bearing portion 22 of the spike plate 20 will contact the small stones 91, and the pressure-bearing portion 22 will be squeezed by the small stones 91 and deformed toward the sole 10, and the deformed pressure-bearing portion 22 will cause the plate ring portion 21 and each of the spike claws 30 to deform synchronously, and cause the claw portion 32 of each of the spike claws 30 to shrink and deform inward synchronously, thereby providing a better gripping effect and effectively preventing slipping.

[0028] See also Figure 5A , Figure 5B and Figure 6 As shown, when the present invention is used on a field 91 without small stones, such as a ridge or a grassy area without small stones, the pressure-bearing portion 22 of the spike plate body 20 is not compressed, and the pressure-bearing portion 22 of the spike plate body 20 is in a normal position, so that the claw portion 32 of each spike claw 30 returns to its original state, and when the claw portion 32 of each spike claw 30 contacts the turf 92, the claw portion 32 of each spike claw 30 is stopped by the turf 92 and squeezed upward, so that the claw portion 32 of each spike claw 30 expands outward, thereby maintaining appropriate grip without excessive force to damage the turf 92.

[0029] Accordingly, the present invention uses the structural design of the spike plate 20 to enable the spike claws 30 to move in conjunction or not depending on the position of the pressure-bearing portion 22 of the spike plate 20. When the present invention is stepped on a field 90 without small stones 91, it maintains appropriate grip without excessive force damaging the turf 92. When stepped on a field 90 with small stones 91, it provides higher grip.
