Assembled aerobic exercising step

Abstract

An assembled aerobic exercising step includes a top plate, a bottom plate, a front plate, a rear plate, a first lateral plate and a second lateral plate. These plates are assembled to form a box-like structure that has an internal storage space. The top plate is movably disposed on the first lateral plate and the second lateral plate. Each plate has a supporting portion. There are a handle and rollers for the user to drag it easily. It is easy to use, good-looking and compact. It can be assembled and disassembled. Many articles can be stored inside this invention. And, the user can drag it easily.

I claim:  
     
         1 . An assembled aerobic exercising step comprising: 
 a top plate, a bottom plate, a front plate, a rear plate, a first lateral plate and a second lateral plate, said top plate being substantially parallel to said bottom plate, said front plate being substantially parallel to said rear plate, and said first lateral plate being substantially parallel to said second lateral plate; said top plate, said bottom plate, said front plate, said rear plate, said first lateral plate and said second lateral plate having several assembling holes respectively;    a plurality of fixing elements for connecting and engaging said top plate, said bottom plate, said front plate, said rear plate, said first lateral plate and said second lateral plate together via said assembling holes, so as to form a box-like structure having an internal storage space; said top plate is movably disposed on said first lateral plate and said second lateral plate;    a plurality of supporting portions disposed on said front plate, said rear plate, said first lateral plate and said second lateral plate respectively, said supporting portions contacting with a bottom surface of said top plate so as to support said top plate;    a handle disposed on an outer surface of said first lateral plate; and    a plurality of rollers disposed on an outer surface of said second lateral plate.    
     
     
         2 . The assembled aerobic exercising step as claimed in  claim 1 , wherein said top plate is hinged on said first lateral plate and said second lateral plate and is rotatable within certain angles.  
     
     
         3 . The assembled aerobic exercising step as claimed in  claim 1 , wherein said first lateral plate has a first sliding slot, and said second lateral plate has a second sliding slot, said top plate having two opposite edges for slidably engaging with said first slot of said first lateral plate and said second slot of said second lateral plate so that said top plate is slidable within certain distance.  
     
     
         4 . The assembled aerobic exercising step as claimed in  claim 1 , wherein a pair of holding recesses are disposed on said first lateral plate and said second lateral plate respectively.  
     
     
         5 . The assembled aerobic exercising step as claimed in  claim 1 , wherein a top surface of said top plate is disposed with an anti-slip portion, said anti-slip portion including a plurality of small protrusions.
