Table with a foldable supporting device

Abstract

A table with a foldable supporting device includes a tabletop and a supporting device provided to support the tabletop. The tabletop has a first face and a second face respectively extending down from a first side and a second side of the tabletop. A limit bar is mounted between the two faces to construct a gap between the limit bar and the tabletop. The supporting device has an H-shaped first leg and an H-shaped second leg pivotally attached to each other. The first leg is pivoted under the tabletop at top ends and the second leg is only abutting under the tabletop at top ends. Thus, the second leg enables to move along the gap between the limit bar and the tabletop via a crosspiece mounted between the two upper ends of the second leg when the table is folded.

What is claimed is:  
     
         1 . A table with a foldable supporting device, comprising: 
 a tabletop with a top, a bottom and edges and including: 
 a skirt extending down from edges of the tabletop and having a first face extending down from one edge of the tabletop and a second face parallel and opposite to the first face and extending down from the other edge of the tabletop; and  
   a supporting device provided to support the tabletop and including: 
 an H-shaped first leg with two upper ends each pivotally connected to the bottom of the tabletop near the first face of the skirt and two lower ends adapted to abut a supporting surface; and  
 an H-shaped second leg pivotally connected to the H-shaped first leg to form an X-shaped structure, the H-shaped second leg having two upper ends abutting the bottom of the tabletop and stopped by the second face of skirt around the edge of the tabletop, and two lower ends adapted to abut the supporting surface;  
   wherein the improvement comprises: 
 the tabletop including a limit bar with two opposite ends respectively secured on the first face and the second face under the tabletop, the limit bar separated from the bottom of the tabletop to define a gap between the limit bar and the bottom of the tabletop; and  
 the H-shaped second leg including a crosspiece with two opposite ends respectively connected to a corresponding one of the two upper ends of the H-shaped second leg and moveably received in the gap between the bottom of the tabletop and the limit bar as the table is folded.  
   
     
     
         2 . The table with a foldable supporting device as claimed in  claim 1 , wherein the limit bar bent to form a recess near the second face of the skirt; and 
 the crosspiece engages in the recess of the limit bar when an upward improper force is applied to the second side of the tabletop.    
     
     
         3 . The table with a foldable supporting device as claimed in  claim 1 , wherein the tabletop further has two L-shaped brackets attached to the bottom of the tabletop for connecting the H-shaped first leg to the tabletop.  
     
     
         4 . The table with a foldable supporting device as claimed in  claim 2 , wherein the tabletop further has two L-shaped brackets attached to the bottom of the tabletop for connecting the H-shaped first leg to the tabletop.
