Patent ID: 8640827

Claim:
An adjustable scaffold base supporting a scaffold tower formed of scaffold frames in an elevated position above a support surface, the scaffold tower having at least four downwardly extending, spaced scaffold tower legs, the scaffold base comprising: (a) first, second, third and fourth elongated, upstanding primary legs in a substantially parallel, spaced relationship with one another, the lower end of each primary leg having an engaging component seating against the support surface; (b) a first lateral beam extending substantially perpendicularly between the first and second primary legs and a second, spaced lateral beam extending substantially perpendicularly between the third and fourth primary legs, each of the primary legs extending through one of four respective substantially parallel primary leg sleeves rigidly affixed to ends of the corresponding lateral beams, whereby each primary leg sleeve slideably surrounds its respective primary leg to permit each lateral beam to move along the length of its respective primary legs except when each primary leg sleeve is removably secured at one of a plurality of positions along the length of its respective primary leg; (c) first and second spaced frame beams extending transversely across, and removably secured between the primary leg sleeves to, the first and second lateral beams; (d) auxiliary leg sleeves rigidly affixed, and substantially perpendicular, to ends of the corresponding frame beams and substantially parallel to the primary leg sleeves; (e) elongated auxiliary legs extending through a respective one of the auxiliary leg sleeves, a lowermost end of each auxiliary leg terminating in a component for engaging the support surface, wherein each auxiliary leg is slidably mounted within its respective auxiliary leg sleeve; and (f) a pair of spaced frame posts extending transversely from each frame beam between the auxiliary leg sleeves and the primary leg sleeves and engaging and supporting the scaffold tower legs.
