Abstract

A stud for sport shoes wherein the shoes are provided with internally threaded sockets for receiving the stud, the stud comprises: a main body portion having an upper and a lower surface; a shank extending outwardly from the upper surface of the body portion and having an outer dimension enabling the same to be threadably received within the threaded sockets of the sport shoe; and a plurality of concentric spaced apart ridges extending outwardly from the lower surface of the body portion to provide traction between the shoe and a supporting surface.

Claims

1. A stud for attachment to the sole of a sport shoe wherein the sole has at least one internally threaded socket for receiving the stud, the stud comprising:

a main body portion formed of a plastic material, said body portion having an upper surface in facing relation to the sole of the sport shoe and a lower surface in spaced and generally parallel relation to the upper surface and in facing relation to a supporting surface;

a cylindrical shank formed of a plastic material, said cylindrical shank being integral with and extending outwardly from the upper surface of said body portion, said cylindrical shank having a smooth outer surface adapted to be threadably received by the threaded socket of the sole of the sport shoe;

a cylinder integral with and extending outwardly from the lower surface of said body portion, said cylinder being defined by a cylindrical side wall and a substantially flat end wall and arranged in coaxial relation with said cylindrical shank wherein the side wall and the end wall meet to form a traction producing circularly extending edge; and

a plurality of spaced apart annular ribs extending outwardly from the lower surface of said body portion to provide traction between the sport shoe and a supporting surface, each of said ribs being concentric with each other and with said cylinder and having spaced apart generally parallel annular side walls extending perpendicularly outwardly of the lower surface of said body portion and terminating in a flat annular end wall wherein the side walls and the flat annular end wall meet to form traction producing annularly extending edges.

2. A stud as claimed in claim 1 wherein said cylindrical shank includes a proximal end adjacent the upper surface of said body portion and a terminal end.

3. A stud as claimed in claim 2 wherein said cylindrical shank tapers inwardly from the proximal end to the terminal end thereof such that the terminal end of said cylindrical shank is narrower than the proximal end to facilitate the self threading thereof as the study is threaded into the internally threaded socket of the sport shoe to which the stud is to be attached.

4. A stud as claimed in claim 1 wherein the upper surface of said body portion is generally concave in respect of the sole of the sport shoe to which it is to be attached.
