a) Field of the Invention
The present invention relates to a thin-type spike intensifying structure, and more particularly to a spike structure which is fixedly assembled at a sole of a sports shoe to intensify an entire spike structure by a creative design of an arc-shape spike sheet made by a thinner plate, especially suitable for a baseball shoe or like.
b) Description of the Prior Art
Due to improvement of a sport quality, and that athletes should be equipped with a strong explosive force in a sport game, all kinds of sports shoes are designed with respect to requirements and features of sports. In terms of a baseball game, a conventional spike structure at a sole of a baseball shoe is usually a plate of an L-shape cross section, which is bended by a predetermined plate through a punch finishing work. The conventional spike structure is shown in
However, for the conventional spike structure, its upright plate b takes on a straight and bended design. As a result, it will usually cause a bending, or even a fracture, to the upright plate b from a strong impacting force in usage, thereby reducing a lifetime of usage of the spike. Accordingly, in order to provide the spike with a sufficient impact tolerance, an iron plate of a thickness of 1.6 mm will often be used on markets for punching into this kind of spike. Nevertheless, the thicker spike is, on the contrary, provided with a shortcoming of being heavier. In addition, as cost of international steel material increases significantly, and in order for the conventional spike to reach a certain extent of structural intensity, the 1.6 mm thick plate has to be used for manufacturing. Besides, cost of a consumable iron plate is also higher correspondingly. Therefore, that conventional product will be in lack of practicability and business competitiveness, which is still undesirable.
Accordingly, the present invention is to provide a thin-type spike intensifying structure which is firm and tolerable, uses a smaller amount of steel, and results in a lighter spike.
The primary object of the present invention is to provide a thin-type spike intensifying structure with a design of an arc-shape spike sheet bended and protruded with an iron plate of a thickness of 0.8 mm, so as to intensify an entire rigid structure and prolong a lifetime of usage of the spike.
Another object of the present invention is to provide a thin-type spike intensifying structure such that an averaged thickness of the spike can be decreased, allowing entire weight of a product to be reduced significantly, thereby reducing a burden to a user and increasing practicability.
Still another object of the present invention is to provide a thin-type spike intensifying structure such that cost of using a raw material can be decreased, so as to increase business competitiveness.
Accordingly, the present invention is made by an integrally formed plate, including an assembly part and a spike sheet, wherein the assembly part is a flat thin plate, on which is provided with an assembly hole for fixing and assembling the spike at a bottom of a sports shoe, and a side of which is bended and protruded with the arc-shape spike sheet. By a creative structure design of the arc-shape spike sheet, the entire rigid structure of the spike can be intensified. On the other hand, at two sides of the spike sheet, close to bended locations, are provided with expanded rims which are extended to the assembly part. In addition, an exterior side of the bended location of the arc-shape spike sheet is provided with a groove, an inner side of which is formed with a ridge having an intensifying effect. Accordingly, the spike is firm and tolerable, and the product is also lighter, thereby increasing the practicability and the advancement.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
Referring to
The aforementioned assembly part 10 is a flat thin plate on which is provided with an assembly hole 11 for fixing the spike 1 on a sole 31 of a sports shoe 30 (as shown in
By the aforementioned structure design, the entire rigid structure of the spike 1 can be intensified, and a product can be made lighter.
