Joint between bed frame and fabric member

Abstract

A joint between a bed frame and a fabric member is revealed. The bed frame includes a plurality of vertical tubes each of which includes an assembly space with a narrow opening. A connection portion connects a plurality of positioning blocks to the fabric member and the positioning blocks are corresponding to the assembly space of each vertical tube. Thereby positioning blocks are mounted into the assembly space from one end of the vertical tube and the connection portion is extending outward through the narrow opening of the vertical tube. Each positioning block is unable to be released from the assembly space axially due to that the outside diameter of the positioning block is larger than the width of the narrow opening. Thus the fabric member and each vertical tube are connected firmly.

What is claimed is: 
     
         1 . A joint between a bed frame and a fabric member comprising:
 a plurality of vertical tubes that form the bed frame; each vertical tube defining an assembly space and having a narrow opening;   the fabric member having a plurality of connection portions whose thickness is smaller than width of the narrow opening and corresponding to the assembly space of the vertical tubes respectively; wherein one side of the connection portion is fixed with a plurality of positioning blocks whose outside diameter is larger than width of the narrow opening; the positioning blocks are mounted into the assembly space from one end of each vertical tube while the connection portion is extending outward through the narrow opening; each positioning block is unable to be released from the assembly space axially.   
     
     
         2 . The device as claimed in  claim 1 , wherein the assembly space is defined on one side of the vertical tube and an extending portion is arranged at one side of the assembly space along an axis of the assembly space; the assembly space having a narrow opening due to disposition of the extending portion.
