Abstract

A spike intended for a golf shoe comprises: a spike body provided with a rear-end flange in a rear-end surface of which a small center hole is provided; a dish-like metallic plate having a central opening and a dish-like concave portion which corresponds in configuration to the rear-end flange of the spike body; and a fixing plate provided with a metallic disk body, a center pin provided in a central portion of the metallic disk body at its front surface so as to be inserted into the small center hole of the spike body, and a threaded shaft provided in a central position of a rear surface of the metallic disk body. In such spike, the spike body is inserted into the central opening of the metallic plate and embedded therein, and receives at the small center hole thereof the center pin of the fixing plate so that the spike body and the metallic plate are assembled and integrally fixed to each other together with the fixing plate by spot-welding a peripheral portion of the fixing plate to the metallic plate.

Claims

1. A spike for sports shoes comprising:

a spike body;

a round dish-like metallic plate;

a fixing plate;

said spike body having a rear-end flange whose rear-end surface is formed with a small center hole;

said round dish-like metallic plate having a central opening for said spike body to be inserted, a dish-like concave portion of such configuration as adapted to receive said rear-end flange and a peripheral edge somewhat curved upward;

said fixing plate having a metallic disk body, a center pin protruding from a front surface of said dish body so as to be inserted in said small center hole, a threaded center shaft protruding from a rear surface of said dish body, and a plurality of small projections for the purpose of being subjected to spot-welding thereon and formed at equal intervals on the vicinity of and along a peripheral edge of said front surface of said disk body and a plurality of radially arranged notches formed on said rear surface; and

at least a pair of through-holes passing through both of said dish-like metallic plate and said fixing plate.

2. A method of assembling a spike for sports shoes, which comprises:

embedding a spike body which includes a small center hole in the central opening of a dish-like metallic plate;

mounting a fixing plate which includes a center pin on said dish-like metallic plate with the center pin inserted in said small center hole;

spot-welding both said fixing plate and said dish-like metallic plate at a plurality of small projections disposed on said fixing plate so as to integrally assemble said fixing plate, said dish-like metallic plate and said spike body;

subjecting said metallic plate to a blanking operating for trimming off its edge portion to provide a round shape;

subjecting said metallic plate to a punching operation together with said fixing plate to provide for through holes for receiving the pin ends of a face spanner;

subjecting said center pin of said fixing plate to a screwcutting operation; and

subjecting the peripheral edge of said metallic plate to a building operation to make it curved upward.
