Adjustable rack device

Abstract

An adjustable rack device includes four base leg members, a base frame engaged onto the base leg members for coupling the base leg members together, four tubular members engaged onto the base leg members and engaged onto the base frame for forming a two-layer structure, a shelf device includes a peripheral frame member and four corner barrels for engaging onto the tubular members, and a table plate may be engaged in the peripheral frame member of the first shelf device. One or more further shelf devices may further be attached onto the barrels for supporting the other table plates.

1 . An adjustable rack device comprising:

       2 . The adjustable rack device as claimed in  claim 1 , wherein said first shelf device includes four pegs attached to said barrels for engaging with and for supporting said table plate. 
   
   
       3 . The adjustable rack device as claimed in  claim 2 , wherein said first shelf device includes at least one cushioning ring attached to each of said pegs for engaging with said table plate. 
   
   
       4 . The adjustable rack device as claimed in  claim 1 , wherein said first shelf device includes a stop extended into each of said barrels for engaging with said tubular members and for allowing said tubular members to be partially engaged into said barrels. 
   
   
       5 . The adjustable rack device as claimed in  claim 1 , wherein said first shelf device includes a head member attached to each of said base leg members and partially engaged into said barrels. 
   
   
       6 . The adjustable rack device as claimed in  claim 1 , wherein said base leg members each include a stud provided thereon and having an outer diameter greater than that of said base leg members for forming a peripheral shoulder in each of said base leg members and for engaging with said barrels. 
   
   
       7 . The adjustable rack device as claimed in  claim 6  further comprising four foot stands detachably attached to said studs of said base leg members. 
   
   
       8 . The adjustable rack device as claimed in  claim 6  further comprising four wheel devices detachably attached to said studs of said base leg members. 
   
   
       9 . The adjustable rack device as claimed in  claim 1  further comprising four posts detachably attached to said base leg members respectively, and four spacers engaged onto said posts respectively and engaged with said barrels of said first shelf device, and a second shelf device engaged on said posts and said spacers. 
   
   
       10 . The adjustable rack device as claimed in  claim 9 , wherein said spacers are partially engaged into said barrels of said first shelf device. 
   
   
       11 . The adjustable rack device as claimed in  claim 9 , wherein said second shelf device includes a peripheral frame member and four barrels provided at four corner areas of said peripheral frame member for engaging onto said spacers. 
   
   
       12 . The adjustable rack device as claimed in  claim 11 , wherein said spacers are partially engaged into said barrels of said second shelf device. 
   
   
       13 . The adjustable rack device as claimed in  claim 11 , wherein said second shelf device includes four pegs attached to said barrels of said second shelf device for engaging with and for supporting a second table plate. 
   
   
       14 . The adjustable rack device as claimed in  claim 13 , wherein said second shelf device includes at least one cushioning ring attached to each of said pegs for engaging with said second table plate. 
   
   
       15 . The adjustable rack device as claimed in  claim 11 , wherein said second shelf device includes a stop extended into each of said barrels for engaging with said spacers and for allowing said spacers to be partially engaged into said barrels of said second shelf device. 
   
   
       16 . The adjustable rack device as claimed in  claim 11 , wherein said second shelf device includes a head member attached to each of said posts and partially engaged into said barrels of said second shelf device. 
   
   
       17 . The adjustable rack device as claimed in  claim 11 , wherein said second shelf device includes at least one handle for handling said adjustable rack device.
