Patent ID: 7770574

Claim:
A wheeled guide assembly for use with cut providing tools, comprising: a) a base portion having a first end and a second end, and rockable between either of a first position, enabling substantially straight-line cuts, and a second position, enabling controlled curved-line cuts; b) a plurality of rollably coupled wheels, including: i) at least two pivot wheels axially aligned and mounted on opposite sides of the base portion, at a selected location between the first end and the second end of the base portion; ii) at least one fixed wheel coupled to one of the first end or the second end of the base portion; and iii) at least one steerable wheel that is rotatably coupled to the base portion at an end opposite to the fixed wheels and structured to enable an operator to rotate the steerable wheel about a vertical axis, for making operator controlled curved-line cuts; c) with the base portion structured for coupling to a cut providing tool and rockable into either the first position or the second position, wherein: i) when in the first position the wheeled guide assembly rolls upon the pivot wheels and the fixed wheels encouraging a substantially straight-line motion, and thereby enabling substantially straight-line cuts to be made with the cut providing tool; and ii) when in the second position the wheeled guide assembly rolls upon the pivot wheels and the at least one steerable wheel supporting a non-linear motion, which is controllable by an operator, for selectively providing non-linear curved-line cuts.
