  • Patent number: 6616132
    Abstract: A planking tool comprising a base, a handle mechanism rotatably attached to the base and a pair of teeth slidably attached to the base wherein the teeth are movable between an engaging position and a disengaging position. A first connecting mechanism attaches the handle mechanism to the pair of teeth. A push plate slidably attached to the base is slidable between an extended position and a withdrawn position. A second connecting mechanism attaches the handle mechanism to the push plate. When the handle is rotated relative to the base the pair of teeth move from the disengaging position to the engaging position while the push plate remains in the withdrawn position. As the handle continues to rotate relative to the base the pair of teeth remain in the engaging position and the push plate moves from the withdrawn position to the extended position.
