Abstract:
A flexible rotary cutting device useful for attaching to a rotary drive configured to trim vegetation, particularly a lawn mower. The flexible rotary cutting device includes a cutting head, an attachment mechanism, at least one cutting-filament retention mechanisms, and at least one cutting-filament. At least one cutting-filament may be releasably attached to the at least one cutting-filament retention mechanism. The at least one cutting-filament may be configured to sever vegetation as the cutting head is rotated, and may be positioned such that it is passed through the at least one filament-aperture, and between the first-filament engaging pawl and the second-filament engaging pawl, in such a way that the at least one cutting-filament is engaged and anchored by the first-plurality of teeth and the second-plurality of teeth, and extends radially from the outer flange of the cutting head.

Claim (Index 1):
A cutting device attachable to a rotary drive configured to trim vegetation, the cutting device comprising:\n a cutting head including\n a disk, \n an outer flange affixed to the disk defining a cylindrical inner volume, \n a cover affixed to the outer flange concentric to the disk, and \n a rotational axis passing through the center of the disk; \n an attachment mechanism affixed to the cutting head for releasably attaching the cutting head to the rotary drive; at least one cutting-filament retention mechanism including\n a first-fulcrum cylinder having a first-fulcrum axis affixed to the cutting head, \n the first-fulcrum axis being parallel but not concentric to the rotational axis, \n a second-fulcrum cylinder having a second-fulcrum axis affixed to the cutting head, the second-fulcrum axis being parallel but not concentric to the rotational axis, \n a first-filament engaging pawl pivotably engaging the first-fulcrum cylinder having a first-plurality of teeth; \n a second-filament engaging pawl pivotably engaging the second-fulcrum cylinder having a second-plurality of teeth, the second-filament engaging pawl minoring the first-filament engaging pawl; \n at least one filament-aperture disposed within the outer flange of the cutting head; and at least one cutting-filament releasably attached to the at least one cutting-filament retention mechanism, the at least one cutting-filament being configured to sever vegetation as the cutting head is rotated, the at least one cutting-filament being passed through the at least one filament-aperture, and between the first-filament engaging pawl and the second-filament engaging pawl, such that the at least one cutting-filament is engaged and anchored by the first-plurality of teeth and the second-plurality of teeth, such that the at least one cutting-filament extends radially from the outer flange of the cutting head.
