ABSTRACT:
A collapsible frame assembly comprises a first frame, a second frame, a first coupler disposed at an end of the first frame, and a second coupler disposed at an end of the second frame. Two angle plates are extended from two sides of a distal end of the first coupler. A press plate is extended from the distal end of the first coupler and positioned between two angle plates. A snap hole is formed on the press plate. A sleeve is inserted in the spacing between two angle plates. Two wing lugs are extended from two sides of a distal end of the second coupler to match the corresponding angle plates. A lower portion of a snap button is inserted in the second coupler and the second frame to match the corresponding snap hole. An inner block is inserted in the second frame to surround the lower portion of the hollow snap button closely. A spring is inserted in the snap button. The second coupler is positioned beneath the press plate. A rivet passes through two wing lugs, two washers, two angle plates and the sleeve. The snap button is inserted in the snap hole.
