ABSTRACT:
A floor covering lifting and removal hand tool for lifting an edge and removing a floor covering that is secured to a floor surface. An arcuate lifting base is formed with a grip end spaced from an opposite end and optionally including load distribution flanges across the arcuate lifting base. An upwardly extending lever arm joins to the arcuate base to rotate the base. The base further incorporates a releasable clamp that captures the edge of the floor covering. Anti-slip features are incorporated about a face of the base to contact the floor covering. In operation, the lever arm is rotated to overcome the force of the bond to lift and remove the floor covering from the floor surface. The lever arm is adjustable, removable, and is optionally ratchetable for use in confined spaces near walls and corners.
