Drift skate

Abstract

A drift skate includes a board and at least one frame which has a connection portion and a cushion installation portion which is connected to the top of the connection portion. Two rollers are respectively connected to the connection portion by two axles. At least two independent cushions are respectively connected between the cushion installation portion and the board by two bolt units. The cushions are functions independently and respond to the action of the board so as to absorb vibration and reaction force from the ground.

What is claimed is: 
     
         1 . A drift skate comprising:
 a board;   at least one frame having a connection portion and a cushion installation portion which is connected to a top of the connection portion;   two rollers respectively connected to the connection portion by two axles, and   at least two independent cushions respectively connected between the cushion installation portion and the board by two bolt units.   
     
     
         2 . The drift skate as claimed in  claim 1 , wherein each of the cushions is located between a bottom sleeve and a top sleeve, the top sleeve is connected to an underside of the board and the bottom sleeve is connected to a top of the cushion installation portion. 
     
     
         3 . The drift skate as claimed in  claim 2 , wherein the bottom sleeve is inserted in the top sleeve, the cushion is completely accommodated between the top and bottom sleeves. 
     
     
         4 . The drift skate as claimed in  claim 1 , wherein each of the cushions is located in the top sleeve which is connected to an underside of the board, a length of the top sleeve at least covers up one half of an axial length of the cushion. 
     
     
         5 . The drift skate as claimed in  claim 1 , wherein each of the cushions is located in the bottom sleeve which is connected to the cushion installation portion, a length of the bottom sleeve at least covers up one half of an axial length of the cushion. 
     
     
         6 . The drift skate as claimed in  claim 1 , wherein each of the two bolt units has a bolt, a washer, a first nut and a second nut, the washer and the first nut are located at an underside of the board and the bolt extends through the board, the washer, the first nut and the cushion installation portion, a distal end of the bolt is connected to the second nut. 
     
     
         7 . The drift skate as claimed in  claim 6 , wherein the bolt has a hexagonal head and the board has a sink hole in which the hexagonal head is received. 
     
     
         8 . The drift skate as claimed in  claim 1 , wherein the cushions are elastic rubber sticks. 
     
     
         9 . The drift skate as claimed in  claim 8 , wherein each of the cushions has an adjustment recess defined in a lower end thereof. 
     
     
         10 . The drift skate as claimed in  claim 8 , wherein each of the cushions has a reception recess defined in a top end thereof.
