Abstract
A foldable supporting frame includes first and second frame units, each with an upper frame, a lower frame, and supports pivotally connected to the upper and lower frames and supporting the upper frame when the foldable supporting frame is unfolded. The foldable supporting frame also includes upper links for pivotally connecting the upper frames of the first and second units and lower links for pivotally connecting the lower frames of the first and second units. Upper and lower links are separated from each other, reducing the overall weight and facilitating smooth folding and unfolding of the supporting frame.
