Abstract
A foldable frame includes first and second units pivotally coupled with each other at their proximal sides and rotatable with respect to each other between a folded state and an unfolded state. The foldable frame also includes a middle leg assembly coupled with the first and second units at the proximal sides of the first and second units. The foldable frame further includes a safety enhancement assembly having a first enhancement member, a second enhancement member and a locking mechanism. The first enhancement member is connected to the first unit and the middle leg assembly. The second enhancement member is connected to the second unit and the middle leg assembly. The locking mechanism selectively locks the first and second enhancement members when the first and second units are in the unfolded state, and thus prevents accidental folding of the first and second units.
