Abstract
This invention discloses portable, collapsible scaffold that is characterized by a substantially planar top platform; a front U-shaped leg structure pivotally connected with the top platform and adapted to fold into a collapsed position that is substantially parallel with and close to the platform; a diagonally extending leg structure pivotally connected with the respective front legs near their top and adapted to fold into a collapsed position; collapsible braces connected near the midpoint to the front legs and the diagonal legs; upper rear U-shaped leg structure that is movable along the bottom of the top platform and adapted to fold into a collapsed position; elongate bracket retaining the rear cross member in close proximity to the platform; and a lock for locking the rear cross member in the supporting position and adapted to prevent collapse of the scaffold until the platform is liftable to release the lock. The respective leg structures are adapted to unfold into a supporting position.
