Connecting piece for folding bedstead

Abstract

A connecting piece for a folding bedstead includes a unit bedstead respectively on the left, right sides thereof Each unit bedstead set includes upper, lower frame sets, each two corresponding cross rods of the two upper frames sets being coupled pivotally to the two corresponding sides of a connecting piece. Furthermore, a support edge is extended toward one side from the lower side in the middle of the connecting piece, allowing the two expanded cross rods to be supported thereon. Thereupon, the present invention is simple in structure and convenient in use, capable of being coupled to the frames on the two sides of a bedstead movably, and furthermore, having a support effect.

I claim: 
     
         1 . A connecting piece for a folding bedstead, said bedstead comprising a unit bedstead set respectively on the right and left sides thereof, each unit bedstead set comprising a upper frame set and lower frame set, some in-between support rods being connected to said upper, lower frame sets, each said frame set comprising two cross rods and two longitudinal rods positioned between said two cross rod, said two unit bedstead sets being coupled to each other through cross rods, characterized in that each said two corresponding cross rods of said two upper frame sets are coupled pivotally to two sides of a connecting piece, a support edge being extended toward one side from a lower side in the middle of said connecting piece, allowing said two expanded cross rods to be support thereon. 
     
     
         2 . The connecting piece according to  claim 1 , wherein a cross beam is configured between said longitudinal rods of each said unit frame, said two cross beams being coupled pivotally to said connecting piece. 
     
     
         3 . The connecting piece according to  claim 1 , wherein said connecting piece is a sheet structure, a pivoting hole allowing said cross rod to be coupled pivotally thereto being respectively configured on two sides of said connecting piece. 
     
     
         4 . The connecting piece according to  claim 3 , wherein a cross beam is configured between said longitudinal rods of each said unit frame, said two cross beams being coupled pivotally to said connecting piece.
