Abstract

A storable structure of the table and chair includes a tabletop and at least one chair member positioned adjacent the tabletop. Each of the at least one chair member includes a chair, a lifting device and a sliding device. The lifting device connects to the chair for vertically moving the chair. The sliding device connects to the lifting device and the tabletop. The chair slides horizontally via the sliding device for storage under the tabletop.

1 . A storable structure of table and chair comprising:
 a tabletop;   at least one chair member positioned adjacent the tabletop, each of the at least one chair member comprising:   a chair;   a lifting device connected to the chair for vertically lifting or lowering the chair, wherein when a force is applied downwardly, the chair is lowered to adapt to abut against a floor, and the chair is lifted upwardly by the lifting device without the force; and   a sliding device connected to the lifting device and the tabletop, wherein the chair slides horizontally under the tabletop via the sliding device for storage.   
     
     
         2 . The storable structure of table and chair as claimed in  claim 1 , wherein the sliding device comprises a guide rail disposed beneath the tabletop and a cantilever having a first portion slidably moved along the guide rail and a second portion connected to the lifting device; the chair moves along the guide rail relatively to the tabletop. 
     
     
         3 . The storable structure of table and chair as claimed in  claim 1 , wherein the chair comprises a seat and a chair base having an upper end pivotally attached to the seat, the chair base sleeved by the lifting device thereon. 
     
     
         4 . The storable structure of table and chair as claimed in  claim 1 , wherein the chair comprises a plurality of casters located underneath the chair for freely moving on the floor. 
     
     
         5 . The storable structure of table and chair as claimed in  claim 1 , wherein the lifting device is a spring member. 
     
     
         6 . The storable structure of table and chair as claimed in  claim 1 , wherein the lifting device is a pneumatic cylinder. 
     
     
         7 . The storable structure of table and chair as claimed in  claim 1 , wherein the lifting device is a set of worm and gear. 
     
     
         8 . The storable structure of table and chair as claimed in  claim 2 , wherein the cantilever has a vertical portion connects to the first portion and second portion. 
     
     
         9 . The storable structure of table and chair as claimed in  claim 2 , wherein the guide rail comprises a T-shaped groove defined therein for receiving the first portion. 
     
     
         10 . The storable structure of table and chair as claimed in  claim 2 , wherein the second portion of the cantilever connects to the lifting device surrounding the chair base for supporting the chair away from the floor. 
     
     
         11 . The storable structure of table and chair as claimed in  claim 8 , wherein the first portion is parallel to the guide rail, the first portion and the second portion both connecting to the vertical portion in an L shape, wherein the first portion is perpendicular to the second portion.
