Receivable roller skate wheel mounting arrangement

Abstract

A receivable roller skate wheel mounting arrangement is constructed to include a sole having two bottom open chambers, and two wheel assemblies respectively mounted in the bottom open chambers, each wheel assembly including a mounting frame fixedly mounted in one bottom open chamber, a wheel holder, the wheel holder having a first pair of upright side lugs respectively pivoted to the mounting frame for enabling the wheel holder to be turned between the extended position and the received position and a second pair of upright side lugs holding a pair of wheels, a spring member provided between the mounting frame and the wheel holder and adapted for holding the wheel holder in the extended position, and lock means adapted for locking the wheel holder between the extended position where the wheels are disposed outside the sole for roller-skating and the received position where the wheels are received inside the corresponding bottom open chamber and the wheel holder close the corresponding bottom open chamber.

What the invention claimed is:  
     
         1 . A receivable roller skate wheel mounting arrangement comprising a shoe, said shoe having a sole, said sole having two bottom open chambers respectively disposed in a bottom sidewall thereof, and two wheel assemblies respectively mounted in said bottom open chambers, said wheel assemblies each comprising a mounting frame fixedly mounted in one bottom open chamber of said sole, a wheel holder pivoted to said mounting frame and holding a pair of wheels and turned between an extended position where said wheels are disposed outside the corresponding bottom open chamber of said sole, and a received position where said wheels are received inside the corresponding bottom open chamber, and a spring member provided between said mounting frame and said wheel holder and adapted for holding said wheel holder in said extended position, wherein said wheel holder comprises two first upright side lugs bilaterally disposed near a first end thereof and respectively pivoted to said mounting frame, two second upright side lugs bilaterally disposed near a second end thereof and adapted for supporting said wheels, and an anti-skid face layer, which is disposed in flush with the bottom sidewall of said sole to close the corresponding bottom open chamber of said sole when said wheel holder is moved to said extended position.  
     
     
         2 . A receivable roller skate wheel mounting arrangement comprising a shoe, said shoe having a sole, said sole having two bottom open chambers respectively disposed in a bottom sidewall thereof, and two wheel assemblies respectively mounted in said bottom open chambers, said wheel assemblies each comprising a mounting frame fixedly mounted in one bottom open chamber of said sole, said mounting frame comprising two downward lugs arranged in parallel at two sides, a wheel holder pivoted to the downward lugs of said mounting frame by pivot means and holding a pair of wheels and turned between an extended position where said wheels are disposed outside the corresponding bottom open chamber of said sole, and a received position where said wheels are received inside the corresponding bottom open chamber, a spring member provided between said mounting frame and said wheel holder and adapted for holding said wheel holder in said extended position, and lock means adapted for locking said wheel holder between said extended position and said received position, wherein said wheel holder comprises two first upright side lugs bilaterally disposed near a first end thereof and respectively pivoted to said mounting frame, said first upright side lugs each having a front retaining notch adapted for receiving said locking means to hold said wheel holder in said extended position and a rear retaining notch adapted for receiving said locking means to hold said wheel holder in said received position, and two second upright side lugs bilaterally disposed near a second end thereof and adapted for supporting said wheels; said locking means comprises a fixed locating rod fixedly fastened to one downward lug of said mounting frame, a barrel suspended between the downward lugs of said mounting frame and sleeved onto said fixed locating rod and adapted for engaging the front retaining notch and rear retaining notch of one upright side lug of said wheel holder alternatively, said barrel having an inner thread in one end thereof, a compression spring mounted in said barrel and stopped against said fixed locating rod, and a pres rod inserted through a side hole of said sole and inserted through an axle hole on one downward lug of said mounting frame opposite to said fixed locating rod and threaded into the inner thread of said barrel and adapted for pressing by hand to disengage said barrel from the upright side lugs of said wheel holder.  
     
     
         3 . The receivable roller skate wheel mounting arrangement as claimed in  claim 2 , wherein the wheel holders of said wheel assemblies each comprise an anti-skid face layer, which is disposed in flush with the bottom sidewall of said sole to close the corresponding bottom open chamber of said sole when the wheel holder of the respective wheel assembly is moved to said extended position.  
     
     
         4 . The receivable roller skate wheel mounting arrangement as claimed in  claim 2 , wherein the wheel holders of said wheel assemblies each comprise at least one friction-resistant stop flange.
