In-line skates

Abstract

An in-line skate includes a boot, a wheel frame, wheels, wheel mounting devices. The wheel frame includes a top mounting board, a first side mounting board, and a second side mounting board. The top mounting board meets with the two parallel side mounting boards, forming an wheel accepting groove, and the side mounting board includes an inner surface forming the groove and an outer surface. The wheel frame includes a plurality of holes provided in the first side mounting board and the second side mounting board of the wheel frame. The wheels mount the wheel-axle assemblies on the side mounting boards of the wheel frame. The wheels are selectively attached on the outer surface of either the first side mounting board or the second side mounting board, or between the inner surfaces of the first side mounting board and the second mounting board.

       2 . The in-line skate of  claim 1 , wherein the boot is mounted on the top mounting board of the wheel frame, wherein the wheel accepting groove extends along the direction of length of the sole of the boot.  
   
   
       3 . The in-line skate of  claim 1  comprising a first wheel, a second wheel, a third wheel, and a fourth wheel.  
   
   
       4 . The in-line skate of  claim 3 , wherein the four (4) wheels are mounted along a straight line in between the inner surfaces of the first side mounting board and the second side mounting board.  
   
   
       5 . The in-line skate of  claim 3 , wherein the first wheel, the third wheel, and the fourth wheel are mounted between the inner surfaces of the first side mounting board and the second mounting board of the wheel frame, and the second wheel is shifted sidewise from the center line of groove to a first direction by being mounted on the outer surface of the first side mounting board.  
   
   
       6 . The in-line skate of  claim 5 , wherein the wheel mounting device further comprises an auxiliary mounting device for mounting the second wheel on the outer surface of the first side mounting board.  
   
   
       7 . The in-line skate of  claim 6 , wherein the auxiliary mounting device comprises a screw of predetermined length.  
   
   
       8 . The in-line skate of  claim 5 , wherein the width of wheel is reduced to a predetermined value.  
   
   
       9 . The in-line skate of  claim 3 , wherein the first wheel and the fourth wheel are mounted between the inner surfaces of the first side mounting board and the second mounting board of the wheel frame, the second wheel is shifted sidewise from the center line of groove to a first direction by mounting on the outer surface of the first side mounting board, and the third wheel is shifted sidewise from the center line of groove to a second direction by mounting on outer surface of the second side mounting board.  
   
   
       10 . The in-line skate of  claim 9 , wherein the wheel mounting device further comprises auxiliary mounting devices for mounting the second wheel on the outer surface of the first side mounting board and for mounting the third wheel on the outer surface of the second side mounting board.  
   
   
       11 . The in-line skate of  claim 10 , wherein the auxiliary mounting device comprises a screw of predetermined length.  
   
   
       12 . The in-line skate of  claim 9 , wherein the width of wheel is reduced to a predetermined value.  
   
   
       13 . The in-line skate of  claim 3 , wherein the second wheel is dismounted to increase the transfer of force and to reduce friction between the wheels and the floor.  
   
   
       14 . The in-line skate of  claim 13 , wherein the third wheel is dismounted further to increase the transfer of force and to reduce friction between the wheels and the floor.  
   
   
       15 . The in-line skate of  claim 1 , wherein the boot further comprises an ankle protecting part.  
   
   
       16 . The in-line skate of  claim 15 , wherein the material of the ankle protecting part of the boots comprises a soft fabric.  
   
   
       17 . The in-line skate of  claim 1 , wherein the wheel comprises a wheel with a narrow floor-contacting point, whereby being adapted to riding on ice.  
   
   
       18 . The in-line skate of  claim 1 , wherein the wheel frame further comprises a second frame provided on the outer surface of the first side mounting board and a third frame provided on the outer surface of the second side mounting board.  
   
   
       19 . The in-line skate of  claim 18 , wherein the second frame and the third frame enclose and provide mounting support to wheels mounted on the outer surfaces of the side mounting boards.
