Flexible cutting line and rotor therefor

In combination, a rotor and a cutting line for a flexible-line lawn trimmer having a drive shaft, said combination comprising:

• a. a body having a peripheral portion and an axial central portion;
• b. means for connecting the central portion of said body with the drive shaft of said lawn trimmer whereby said rotor body is bodily rotated;
• c. a first entry opening and a first exit opening;
• said exit opening being positioned substantially radially through the peripheral portion of said body;
• d. means communicatively joining said first entry and first exit openings with an angular relationship therebetween;
• e. a first flexible cutting line threaded through said first entry and exit openings and having an enlarged end and a free end;
• said enlarged end being adjacent to and outwardly of said first entry opening, abuttingly engaging said body, and separably anchoring said first flexible cutting line in said body;
• said free end extending outwardly of said first exit opening and being of suitable length for cutting vegetation in response to rotor rotation;
• f. said means communicatively joining said first entry and exit openings comprises a first elongate passageway within said body;
• g. said first flexible cutting line is disposed within said first passageway;
• h. said entry and exit openings are positioned apart and at an angular relationship;
• i. said first elongate passageway has a curvilinear shape;
• j. said body comprises a base portion separably connected with a hub portion;
• k. said base has a disc shape and includes at least one flange segment projecting from an outer peripheral surface of said base;
• said first entry and exit openings being positioned radially through said flange segment;
• l. said hub has a disc shape and cooperatingly engages said base, and includes a slot in a peripheral edge portion thereof wherein said flange portion is positioned and mates therewith, said first elongate passageway being positioned within said hub and having a channel shape with an open end thereof being coextensive with an inwardlymost surface of the hub;
• and
• m. means separably interconnecting said base with said hub.

In combination, a rotor and a cutting line for a flexible-line lawn trimmer having a drive shaft, said combination comprising:

• a. a body having a peripheral portion and an axial central portion;
• b. means for connecting the central portion of said body with the drive shaft of said lawn trimmer whereby said rotor body is bodily rotated;
• c. an entry opening and an exit opening;
• said exit opening being positioned generally radially through the peripheral portion of said body;
• d. means communicatively joining said entry and exit openings with an angular relationship therebetween;
• e. a flexible cutting line threaded through said entry and exit openings and having an enlarged end and a free end;
• said enlarged end being adjacent to and outwardly of said entry opening, abuttingly engaging said body, and separably anchoring said flexible cutting line in said body;
• said free end extending outwardly of said exit opening and being of suitable length for cutting vegetation in response to rotor rotation;
• f. said entry and exit openings are positioned apart and at an angular relationship;
• g. said means communicatively joining said entry and exit openings comprises an elongate passageway within said body, said elongate passageway having an entry portion and an exit portion extending into said body from the entry and exit openings respectively and a curved portion connecting said entry portion and exit portion of said elongate passageway and permitting a cutting line free end to be inserted into said entry opening and move through said elongate passageway and out the exit opening to extend therefrom with the enlarged end abutting said body at the inlet opening.
