Bench folding mechanism for picnic tables

Abstract

A bench folding mechanism for picnic tables, including two parallel tube members installed at the ends of collapsible table legs on two sides under a tabletop, the benches on two sides each have bench legs that are selectively folded inwardly. At the end of the table leg is installed a telescopic tube inserted into a tube member at the end of the table leg. Thereby, the benches are capable of being extended outside the tabletop or retracted under the tabletop. When the benches are folded under the tabletop, the table legs and bench legs are simultaneously folded inwardly under the tabletop, and the benches are folded to two sides under the tabletop. Therefore, the size of the entire picnic table can be reduced to almost the cubic measurements of the tabletop. The invention provides convenience in handling, storing and transportation of the picnic table.

What is claimed is:  
     
         1 . A bench folding mechanism for picnic tables, comprising a tabletop having table legs, and benches with bench legs on two sides of the tabletop, wherein: 
 the tabletop has a frame attached to a rear side thereof, opposing table legs joined to two sides of the frame, a rack holder attached to a center on the rear side of the tabletop, and connecting rods and a Y racks connected between the rack holder and the table legs;    the benches each have foldable bench legs on two sides of a bottom side thereof, characterized in that:    at each end of the table leg are attached two parallel tube members;    at two sides of a bottom side thereof are attached foldable bench legs, at an end of the bench leg being a telescopic tube, the telescopic tube extending into a corresponding tube member installed at an end of the table leg;    telescoping of the telescopic brings the benches, along with the bench legs, to retract under the tabletop.    
     
     
         2 . The bench folding mechanism for picnic tables as defined in  claim 1 , wherein, the bench has on a rear side thereof two opposing tube supports, between two sides of two tube supports being a U-joint, with one end of the bench leg connected to the U-joint, a slide slot installed on an inside of two sides of the tube supports, an end of an additional reinforcing rack connected to a middle of the bench leg, a guide rod installed at another end of the reinforcing rack, so configured that two ends of the guide rod is capable of sliding inside the slide slot.
