Abstract
Disclosed are supports, folding mechanisms and foldable supporting frames. A foldable supporting frame includes a plurality of bent bars, folding mechanisms and supports. The bent bars are connected to each other by the folding mechanisms and the supports to form upper and lower frames of the foldable supporting frame. The foldable supporting frame can be folded and unfolded by rotating any one of the bent bars. When unfolded, the supports hold the upper frame in place and keep it flat and stable. When folded, the folding mechanisms and the supports allow the bent bars to move toward each other and fold onto each other. The folded supporting frame is compact and of a regular shape, making it easier to handle, package, store, and transport.
