Separable chair assembly

Abstract

This invention relates to a method for manufacturing a separable chair assembly, in particular a type of chair assembly which can be separated, folded, overlapped for storage with least space, characterized in that the chair assembly consists of one back unit and one seat unit, closed matched. The back unit and the seat unit are in an H form with slight curvature looked from a side view. The back unit is designed wider than the seat unit, so the chair assembly can be folded in one piece when not in use. The back unit is furnished with a front retaining board and a rear retaining at the center part. While in use, the back unit and the seat unit will cross each other so as to set the seat unit leaning on the retaining boards thus to form a chair. It is a practicable application for use.

What is claimed is:  
     
         1 . A separable chair assembly, mainly comprising a back unit and a seat unit characterized in that: 
 said back unit and said seat unit have two slightly curved back stretchers arranged with a plurality of parallel cross slats to form an H form, a retaining board is installed at a certain distance downward from a lowest slat of said seat back, and a corresponding retaining board is installed at back of said lowest slat, thus said retaining boards are in staggered to position, permitting limited seats for use.    
     
     
         2 . The separable chair assembly of  claim 1 , wherein 
 said slat shall keep a gap from said retaining board wide enough to allow free insert of said seat unit.    
     
     
         3 . The separable chair assembly of  claim 1 , wherein stretchers at two sides of said back unit are designed with lower grooves and said retaining boards are glued and bolted in said grooves in an effort to gain strong support and weight distribution.  
     
     
         4 . The separable chair assembly of  claim 1 , wherein a chair assembly can be expanded in transverse direction by enlarging size of said slats and retaining boards of said back unit and said seat unit and adding additional stretchers to enhance strength and make said chair assembly a multiple seat chair.  
     
     
         5 . The separable chair assembly of  claim 1 , wherein stretcher, replacing said back unit and seat unit, are bracketed across each other, and a table leaf is placed on top of said stretchers to form a simplified table.
