Adjustable roller skate

Abstract

An adjustable roller skate includes an adjustable sole assembly, a lock, a cover assembly and a wheel assembly. The adjustable sole assembly includes a rear sole and a front sole. The rear sole is formed with a transverse wall. The front sole includes a longitudinal bar extending from a rear end thereof and a transverse bar extending from the longitudinal bar. When the front sole is moved far enough from the rear sole, the transverse bar abuts the transverse wall to prevent excessive movement of the front sole from the rear sole. The lock is used to lock the front sole in a desired position relative to the rear sole. The cover assembly includes a heel cover formed on the rear sole and a toe cover formed on the front sole. The wheel assembly includes a chassis connected to the rear sole and wheels connected to the chassis.

1 . An adjustable roller skate including:
 an adjustable sole assembly including a rear sole formed with a transverse wall and a front sole with a first longitudinal bar extending from a rear end thereof and a transverse bar extending from the first longitudinal bar, wherein when the front sole is moved far enough from the rear sole, the transverse bar abuts the transverse wall to prevent excessive movement of the front sole from the rear sole;   a lock for locking the front sole in a desired position relative to the rear sole;   a cover assembly including a heel cover formed on the rear sole and a toe cover formed on the front sole; and   a wheel assembly including a chassis connected to the rear sole and wheels connected to the chassis.   
     
     
         2 . The adjustable roller skate according to  claim 1 , wherein the rear sole includes a longitudinal wall placed against the first longitudinal bar to render smooth the movement of the front sole relative to the rear sole. 
     
     
         3 . The adjustable roller skate according to  claim 1 , wherein the front sole includes a second longitudinal bar extending parallel to the first longitudinal bar and including bores defined therein, wherein the lock includes a peg for insertion in a selected one of the bores to lock the front sole in a selected one of several positions relative to the rear sole. 
     
     
         4 . The adjustable roller skate according to  claim 3 , wherein the lock includes a carrier movably connected to the rear sole, wherein the peg is connected to the carrier. 
     
     
         5 . The adjustable roller skate according to  claim 4 , wherein the rear sole includes a groove for receiving the carrier. 
     
     
         6 . The adjustable roller skate according to  claim 5 , wherein the lock includes a spring compressed between the closed end of the groove and the carrier so that the moveable element is biased by the spring. 
     
     
         7 . The adjustable roller skate according to  claim 4 , wherein the carrier includes a block formed at an end, a button formed at another end, and a gap defined between the block and the button, wherein the peg is connected to the block. 
     
     
         8 . The adjustable roller skate according to  claim 7 , wherein the block includes a tunnel defined therein, wherein the peg is partially inserted in the tunnel. 
     
     
         9 . The adjustable roller skate according to  claim 8 , wherein the block includes a shoulder formed on the wall of the tunnel, wherein the peg includes a shoulder placed against the shoulder of the block. 
     
     
         10 . The adjustable roller skate according to  claim 7 , wherein the lock includes a spring for biasing the block. 
     
     
         11 . The adjustable roller skate according to  claim 7 , wherein the rear sole includes a groove for receiving the carrier, wherein the groove includes a closed end and an open end through which the button extends beyond the rear sole. 
     
     
         12 . The adjustable roller skate according to  claim 11 , wherein the lock includes a spring compressed between the closed end of the groove and the carrier so that the moveable element is biased by the spring. 
     
     
         13 . The adjustable roller skate according to  claim 1 , wherein the wheels are arraigned in two pairs. 
     
     
         14 . The adjustable roller skate according to  claim 1 , wherein the wheels are arranged in a line. 
     
     
         15 . The adjustable roller skate according to  claim 1 , wherein the rear sole includes at least two fins extending from a lower face, wherein the chassis is placed between and connected to the fins. 
     
     
         16 . The adjustable roller skate according to  claim 15 , wherein each of the fins includes an aperture defined therein, wherein the chassis includes an aperture defined therein, wherein the lock includes a screw driven into the aperture of the chassis through the apertures of the fins.
