Patent ID: 7603782

Claim:
A flexible line trimming system for cutting grass, weeds and the like, comprising: a powered device providing rotary power at a power end; a flexible trimmer line head add-on attached to the power end of said powered device for rotation, said trimmer line head add-on including: a protective base (D 2 ), a main trimmer head substrate (D 3 ) attached to said protective base on its bottom side forming a combined substrate and base, and having an upper side, and a series of at least two, peripherally spaced, line holders attached to said upper side of said trimmer head substrate with the attachment allowing said line holders to oscillate back and forth about respective vertical axes and located adjacent to the periphery of said trimmer head substrate spaced a hundred and eighty (180°) degrees apart from one another, said line holders each having a series of at least two, spaced but adjacent, parallel holes extending from end-to-end completely through said line holder, with the material between said two holes serving as a central member about which a bent back, flexible trimming line is positionable with the central crook of the bent back line being wrappable around said central member and with the rest of the line segments positionable in and extending completely through said openings with the distal ends of the flexible trimming line extending out of and past said line holders and said periphery of said combined base and substrate, wherein said base, said substrate and said line holders, attached together as an integral unit, are rotated at a relatively high speed by the powered device, causing trimming lines to move straight, radially out under the action of centrifugal force but allowing the trimming lines to move backwards due to impeding forces causing its respective line holder to oscillate back a limited amount while the integral unit is rotated at a relatively high speed by the powered device.
