Tri-functional carrier

Abstract

A tri-functional carrier formed by a plurality of rods bending at two sides is disclosed. The tri-functional carrier is formed by a retainer, a driven unit being pivotally engaged to the retainer, a supporting unit pivotally engaged to one end of the retainer. By the aforesaid structure, after a frame of the tri-functional carrier is folded, it can be converted into a back frame, a chair or a baggage carrier which is stored and located easily.

What is claimed is:  
     
         1 . A tri-functional carrier formed by a plurality of rods bending at two sides, wherein: 
 the tri-functional carrier is formed by a retainer, a driven unit being pivotally engaged to the retainer, a supporting unit pivotally engaged to one end of the retainer, by the aforesaid structure, after a frame of the tri-functional carrier is folded, it can be converted into a back frame, a chair or a baggage carrier which is stored and located easily.    
     
     
         2 . The tri-functional carrier as claimed in  claim 1 , wherein the retainer has one end being installed with an axial rod; two sides of the axial rod is installed with respective sliding elements; two sides of the retainer are installed with respective pins; and a pull strip serves to connect the two pins.  
     
     
         3 . The tri-functional carrier as claimed in  claim 1 , wherein the retainer is installed with a buckle and a back strip having a back pad.  
     
     
         4 . The tri-functional carrier as claimed in  claim 1 , wherein the driven unit is installed with sliders; the driven unit is engaged with the sliders by a cross bar; a load portion is supported across the driven unit and the cross bar; one end of the driven unit is installed with a supporting frame; and one side thereof is installed with a hook.  
     
     
         5 . The tri-functional carrier as claimed in  claim 1 , wherein a beating portion with a buckle runs across the driven unit and the cross bar.  
     
     
         6 . The tri-functional carrier as claimed in  claim 1 , wherein the load portion and the back pad are made by one selected from a group containing canvas or flannelette.  
     
     
         7 . The tri-functional carrier as claimed in  claim 1 , wherein two sides of the supporting unit are installed with fixing portions, respectively, and one end of the supporting unit is installed with a sliding stopper.
