Patent ID: 7882642

Claim:
A trimmer head for use with a length of flexible cutting line in a flexible line rotary trimmer, said head comprising: a housing adapted to be operatively connected to a rotary trimmer to effect rotation of the head, said housing defining a cylindrical depending skirt having opposed line openings therein; and a spool for carrying a length of cutting line thereon, said spool being operatively connected to said housing for rotation therewith about a common axis, said spool including a cylindrical body portion, at least one flange projecting radially therefrom so as to define at least one cutting line storage area about said body portion adjacent said flange and a line receptor channel traversing said spool, said channel defining opposed open ends radially alignable with said line openings in said housing skirt upon relative rotation of said spool and said housing and an open portion intermediary of said opposed open ends so as to provide access to said channel intermediary of said open ends with said spool operatively connected to said housing, enabling a user to insert a length of cutting line through said receptor channel and the aligned openings in the housing skirt and wrap the length of line about the spool without having to interrupt the operative connection between the spool and the housing, and in the event of a line breakage proximate one or both of said line openings in the housing skirt, the user can grip and pull on the line in the open portion of said channel in a direction away from said spool and generally parallel to said common axis whereby the cutting line on said spool is pulled from the head for replacement without having to interrupt the operative connection between the spool and the housing.
