Foldable Adjustable Bed Frame

原文（中国語）

A foldable and adjustable one-piece King and California King bed frame that includes a bottom frame and a multi-sectional adjustable frame having left and right extension portions that allow the frame to adjust between King and California King sized beds, and allows the bed to be folded to a relatively small size for shipping. The adjustable frames have two transverse extension portions and a longitudinal rod connected with the two transverse extension portions, and the extension frames have two support arms and two stopping portions disposed with the two support arms, and two linkages each having two ends pivotally connected with the associated transverse extension portion and support arm in a way that the two linkages are abutted against top edges of the stopping portion and longitudinal rod. The extension frame is upwardly foldable together with the linkages to swing to the top side of the adjustable frames to reduce the width of the frame, and when they are folded down also minimize the thickness of the folded frame. As a result, the package size of the bed frame may be classified into a lower charging category for transportation, thereby reducing costs and enhancing market competitiveness
