Shoe spike with elasticity and grip

Abstract

The invention provides a shoe spike with elasticity and grip, comprising a mounting part arranged at the bottom of a shoe sole, wherein the bottom of the mounting part is provided with a guiding column, and the top of the guiding column is clamped into the inside of the mounting part; an elastic part is provided on the bottom of the mounting part and on the surface of the guiding column, and the elastic part is hollow. When the wearer steps on the ground to make the ground contacting part contact the ground and receives pressure, the elastic part and the ground contacting part move upwards along the guiding column for a certain distance synchronously; the elastic part shrinks and produces elastic deformation, thereby generating elastic force; the ground contacting part is made of hard material, which produces sufficient grip.

1 . A shoe spike with elasticity and grip, comprising a mounting part ( 1 ) arranged at the bottom of a shoe sole ( 9 ), wherein the bottom of the mounting part ( 1 ) is provided with a guiding column ( 2 ), and the top of the guiding column ( 2 ) is clamped into the inside of the mounting part ( 1 ); an elastic part ( 3 ) is provided on the bottom of the mounting part ( 1 ) and on the surface of the guiding column ( 2 ), and the elastic part ( 3 ) is hollow; the bottom of the elastic part ( 3 ) is provided with a hard ground contacting part ( 4 ); the bottom end of the guiding column ( 2 ) extends into the ground contacting part ( 4 ). 
     
     
         2 . The shoe spike with elasticity and grip according to  claim 1 , wherein the elastic part ( 3 ) and the ground contacting part ( 4 ) are bonded and formed by over-molding. 
     
     
         3 . The shoe spike with elasticity and grip according to  claim 1 , wherein the guiding column ( 2 ) comprises a mounting piece ( 21 ) at the top and a guiding rod ( 22 ) arranged vertically at the bottom of the mounting piece ( 21 ); the top of the mounting piece ( 21 ) is provided with a boss ( 23 ); the diameter of the guiding rod ( 22 ) and the boss ( 23 ) are both smaller than the diameter of the mounting piece ( 21 ). 
     
     
         4 . The shoe spike with elasticity and grip according to  claim 3 , wherein the middle part of the elastic part ( 3 ) is vertically penetrated with a through hole ( 7 ); the upper surface of the ground contacting part ( 4 ) is provided with a downwardly recessed groove ( 8 ); the diameter of the groove ( 8 ) is the same as the diameter of the through hole ( 7 ), and the diameter of the groove ( 8 ) and the diameter of the through hole ( 7 ) are adapted to the diameter of the guiding rod ( 2 ). 
     
     
         5 . The shoe spike with elasticity and grip according to  claim 4 , wherein the diameter of the through hole ( 7 ) is smaller than the diameter of the mounting piece ( 21 ). 
     
     
         6 . The shoe spike with elasticity and grip according to  claim 1 , wherein the bottom of the ground contacting part ( 4 ) is provided with a plurality of protrusions ( 6 ).
