ABSTRACT:
A foldable stand for supporting a machine can be folded or extended between a collapsed position, an extended supporting position, and a hand carrying position. The foldable stand includes a platform formed by two bearing bars that define a bearing surface for supporting a machine. Two support units are pivotally connected to the bearing bars and can be pivoted, and selectively locked, between a collapsed position, an extended supporting position, and a hand carrying position. The selective locking is achieved by the selective engagement of positioning devices with locating grooves formed on the foldable stand.
