Foldable seat

Abstract

A foldable seat ( 10 ) includes a brace ( 1 ) and a top ( 2 ). Front and rear leg assemblies ( 11, 12 ) of the brace ( 1 ) are each U-shaped pipes, with open ends of the “U” serving as feet and strengthening poles ( 111, 114, 124 ) fixed across the open ends. Four connectors ( 3 ) are fixed to the front and rear leg assemblies ( 11, 12 ). Each connector ( 3 ) has a slide notch ( 31 ) which extends horizontally. Two top and two bottom side-support bodies ( 13, 131, 132 ) of the brace ( 1 ) are U-shaped pipes, with the open ends having spring fasteners ( 130 ). The ends of side-support bodies ( 13 ) fit into the connectors ( 3 ), and the spring fasteners ( 130 ) are free to pivot therein due to the slide notches ( 31 ) to permit folding between a closed and an open position. A top ( 2 ) clips to the brace through clips ( 21, 22 ).

1 . A foldable seat comprising: 
 a brace having front and rear U-shaped leg assemblies with ends of said U-shaped leg assemblies forming feet, said brace having at least two side-support bodies formed from U-shaped pipes pivotally coupled to said front and rear leg assemblies through four pipe-shaped connectors, wherein said connectors are fixed to said leg assemblies and two ends of each of said side-support bodies are inserted into and held within two of said four connectors, said side-support bodies being held within said connectors by spring fasteners located proximate ends of said side-support bodies, and each of said connectors includes a horizontally-extending slide notch within which said spring fastener moves as said support bodies pivot relative to said leg assemblies; and    a top removably coupled to said brace.    
   
   
       2 . A foldable seat as claimed in  claim 1  wherein said brace includes at least four side-support bodies, each connector connects an upwardly-extending side-support body and a downwardly-extending side-support body.  
   
   
       3 . A foldable seat as claimed in  claim 1  additionally comprising four a plastic coverings, wherein each plastic covering is inserted between one of said side-support bodies and one of said connectors so that said side-support bodies tightly fit within said connectors.  
   
   
       4 . A foldable seat as claimed in  claim 1  wherein said top is a blow-molded panel having a bottom surface with a concave dent in which a plurality of ribs are located.  
   
   
       5 . A foldable seat as claimed in  claim 1  additionally comprising a back fixed to a back pole that is fixed to said rear leg assembly, said back pole being formed from a U-shaped pipe, and said back being a blow-molded panel.  
   
   
       6 . A foldable seat as claimed in  claim 1  additionally comprising four extendable pipes, with each of said extendable pipes being positioned at a foot-end of said front and rear leg assemblies, said extendable pipes being held to said foot-ends of said front and rear leg assemblies by spring fasteners positioned in said front and rear leg assemblies which mate with a hole selected from a plurality of holes formed on each extendable pipe.  
   
   
       7 . A foldable seat as claimed in  claim 1  additionally comprising two strengthening poles, with each of said strengthening poles being fixed at an open end of one of said U-shaped front and rear leg assemblies.  
   
   
       8 . A foldable seat as claimed in  claim 1  wherein said front and rear leg assemblies, said side-support bodies, and said connectors are formed of steel, and said connectors are fixed to said front and rear leg assemblies by welding.  
   
   
       9 . A foldable seat as claimed in  claim 1  additionally comprising a plurality of clips fixedly attached to a bottom side of said top and configured to removably attach to said front and rear leg assemblies and to said side-support bodies.  
   
   
       10 . A foldable seat as claimed in  claim 9  wherein said clips are integrally formed with said top.  
   
   
       11 . A foldable seat comprising: 
 a front U-shaped leg assembly wherein open ends of said front U-shaped leg assembly serve as feet for said seat;    a rear U-shaped leg assembly wherein open ends of said rear U-shaped leg assembly serve as feet for said seat;    first and second pipe-connectors rigidly fixed to said front U-shaped leg assembly, said first and second pipe-connectors each having a circumferentially extending slide notch;    third and fourth pipe-connectors rigidly fixed to said rear U-shaped leg assembly, said third and fourth pipe-connectors each having a circumferentially extending slide notch;    a first U-shaped side-support body having two ends with a spring fastener projecting outward proximate each of said first side-support body ends, wherein each of said spring fasteners is configured to mate with one of said slide notches; and    a second U-shaped side-support body having two ends with a spring fastener projecting outward proximate each of said second side-support body ends,    wherein said first and second side-support bodies couple to said pipe-connectors so that said spring fasteners in said side-support bodies mate with said slide notches in said pipe-connectors, are free to pivot within said slide notches, and are prevented from moving vertically.
