Abstract:
A line trimmer head for cutting vegetation comprising:a central hub having a bore formed thereon aligned along a central axis;a body including an annular disc extending circumferentially radially outward from tie central hub in a plane generally perpendicular to the central axis, the disc having a generally uniform thickness outer peripheral rim having a smooth uninterrupted upper and lower outer peripheral edges which extend about the entire 360.degree. periphery of the desk and at least one pair of circumferential spaced apart closed tubular openings extending through the peripheral rim between the upper and lower outer peripheral edges for receiving a length of line which is radially threaded therethrough with each of closed tubular openings being aligned generally radially to the central longitudinal axis; andat least one pair of retainers oriented on the disc for retaining the line in place, each retainer having a hook shape portion having an incline ramp formed on the underside of the hook shape portion for engaging the line securely against the ramp as a result of tension in the line caused by centrifugal force as the head is rotated about the central longitudinal axis.
