Abstract:
A walk-behind apparatus and method for cutting non-linear trenches in concrete includes a frame supported by fixed direction wheels at a front end on a fixed axis of rotation, and multi-directional wheels at a rear end to rotate on movable axes of rotation, to permit the frame to rotate about a vertical axis passing through the frame. A handle is engageable by a user walking behind the frame for pushing the apparatus forward and/or for steering. A cutting wheel has a diameter of 5-20 inches and a cutting portion having a width of 0.5-1.5 inches. The cutting rotates on an axis parallel to the fixed axis and which extends notionally through the fixed direction wheels. The cutting wheel is disposed within a protective shroud viewable by the user to permit the user to visually align and guide the cutting wheel along a non-linear path on the ground while steering.

Claim (Index 1):
A walk-behind apparatus for cutting non-linear trenches in concrete, the apparatus comprising:\n a frame supported by at least three ground engaging wheels, the frame including:\n one or more fixed direction wheels at a front end portion of the frame disposed to rotate on a fixed axis of rotation; and \n one or more multi-directional wheels at a rear end portion of the frame disposed to rotate on one or more movable axes of rotation; \n wherein the at least three ground engaging wheels define an x-y plane and permit the frame to rotate about a z-axis passing through the frame normal to the x-y plane; \n a user-engageable handle disposed at the rear end portion of the frame, the handle being engageable by a user walking behind the frame for pushing the apparatus forward and/or for steering the apparatus by pushing the handle left or right; a motor-driven ground-engaging cutting wheel having a cutting wheel axis of rotation, a diameter D in a range of from about 5 inches to about 20 inches, with a cutting portion having a width w in a direction parallel to said cutting wheel axis of rotation within a range of from about 0.5 inches to about 1.5 inches; the cutting wheel axis of rotation being substantially parallel to said fixed axis of rotation and extending notionally through said one or more fixed direction wheels; the cutting wheel being disposed within a substantially disc-shaped protective shroud sized and shaped to contain a majority of the cutting wheel therein during said operation, the protective shroud disposed in view of the user while engaging the handle, to permit the user to visually align the shroud and cutting wheel with a non-linear path on the ground during said pushing and steering to guide the cutting wheel along the non-linear path.
