Combined folding table and seat assembly

In a collapsible combined table and seat of the type wherein said seat and table are relatively pivotally movable between an open position wherein said table and seat are horizontal and the front edge of said seat is disposed adjacent and below one end of said table and a folded position wherein said seat is in confronting substantially parallel relation with said table, an improved collapsible linkage for supporting said table and seat in said open position and for permitting said pivotal movement to said folded position, said linkage comprising:

• a support member, a pivot for connected one end of said support member to said table adjacent said one end of said table for movement between an open position in which said support member extends downwardly from said table and a closed position in which said support member is in confronting parallel relation with the bottom surface of said table;
• a leg, another pivot for connecting said leg to the end of said support member opposite said one end thereof for movement between an open position in which said leg extends downwardly from said support member and a closed position in which said support member and said leg are in confronting substantially parallel relation;
• said seat being pivotally mounted on said leg for movement between an open position in which said seat extends horizontally from said leg when said leg and said support member are in their open position and a closed position in which leg and said seat are in confronting substantially parallel relation;
• means for holding said seat in said open position;
• and
• a longitudinally extending sleeve slidably mounted on said support member for movement between an unlocking position wherein said sleeve is out of overlapping relation with said other pivot to permit pivotal movement between said support member and said leg and a locking position wherein said sleeve overlies said other pivot to prevent movement thereabout.
