Shelf device

Abstract

A shelf device includes a plurality of leg rod units that are upright and that extend in a top-bottom direction, a plurality of shelf units that are spaced apart from each other in the top-bottom direction and that are mounted to the leg rod units, and at least one supporting unit that is removably connected between an adjacent pair of the leg rod units.

What is claimed is: 
     
         1 . A shelf device comprising:
 a plurality of leg rod units that are upright and that extend in a top-bottom direction;   a plurality of shelf units that are spaced apart from each other in the top-bottom direction and that are mounted to said leg rod units; and   at least one supporting unit that is removably connected between an adjacent pair of said leg rod units.   
     
     
         2 . The shelf device as claimed in  claim 1 , wherein:
 said at least one supporting unit includes a plurality of supporting units, each of said supporting units being removably connected between a corresponding adjacent pair of said leg rod units, and including
 two supporting rods that are spaced apart from each other and that are connected respectively to said corresponding adjacent pair of said leg rod units, and 
 a connection set that is connected between said supporting rods, and that includes
 a first connecting member spaced apart from said supporting rods, and 
 two second connecting members, each removably connected between said first connecting member and a respective one of said supporting rods. 
 
   
     
     
         3 . The shelf device as claimed in  claim 2 , wherein, for each of said supporting units, at least one of said second connecting members of said connection set is removably inserted into said first connecting member and is movable relative to said first connecting member so as to change a length of said connection set. 
     
     
         4 . The shelf device as claimed in  claim 3 , wherein, for each of said supporting units, said second connecting members of said connection set are respectively and removably inserted into two opposite ends of said first connecting member, and are movable relative to said first connecting member so as to change the length of said connection set. 
     
     
         5 . The shelf device as claimed in  claim 4 , wherein, for each of said supporting units, each of said second connecting members is threadedly and removably inserted into said first connecting member, and is threadedly movable relative to said first connecting member so as to change a total length of portions of said second connecting members that are disposed outside of said first connecting member. 
     
     
         6 . The shelf device as claimed in  claim 5 , wherein, for each of said supporting units, each of said second connecting members has a threaded body portion that is threadedly and removably inserted into said first connecting member, and a connecting head portion that is hooked by the respective one of said supporting rods. 
     
     
         7 . The shelf device as claimed in  claim 6 , wherein, for each of said supporting units, each of said supporting rods has:
 a first end hook that is hooked to the respective one of said corresponding adjacent pair of said leg rod units; and   a second end hook that is opposite to said first end hook, said connecting head portion of each of said second connecting members being hooked by said second end hook of the respective one of said supporting rods.   
     
     
         8 . The shelf device as claimed in  claim 7 , wherein:
 each of said leg rod units includes a leg rod and a coupling member disposed on said leg rod; and   for each of said supporting units, said first end hook of each of said supporting rods is hooked to said coupling member of the respective one of said corresponding adjacent pair of said leg rod units.   
     
     
         9 . The shelf device as claimed in  claim 8 , wherein, for each of said leg rod units, said coupling member is formed in one of a U-shaped configuration, a V-shaped configuration, and a C-shaped configuration.
