Abstract
A flexible nonmetallic line trimmer for cutting vegetation has a wheel support for edging operations. The trimmer has a safety guard that extends around the rearward portion of a motor housing. A sliding bracket is mounted to the safety guard. A wheel is mounted on the forward end of the sliding bracket. The bracket will slide between a retracted position with the wheel to one side of the housing to an extended position with the wheel in front of the housing to support the cutter.
Claims11
In a line trimmer for cutting vegetation of the type having a housing, a head mounted to the housing for rotation about an axis, a flexible nonmetallic line extending outwardly from the head in a cutting plane generally perpendicular to the axis, and a safety guard mounted to the housing extending around a rearward portion of the cutting plane, the improvement comprising:
- a single wheel having an axis of rotation and adapted to be placed in contact with the ground;
- and
- mounting means for mounting the wheel to the cutter with the axis of rotation of the wheel substantially parallel with the axis of the head and for selected movement in a plane substantially perpendicular with the axis of the head between a retracted inoperative position with the wheel to one side of the housing and the trimmer suspended above ground for trimming operations, and an extended operative position forwardly of the safety guard for rolling contact on the ground for supporting the cutter with said axis of the head in a substantially horizontal plane above the ground for edging.
In a line trimmer for cutting vegetation of the type having a housing, a head mounted to the housing for rotation about a motor axis, a flexible nonmetallic line extending outwardly from the head in a cutting plane, and a safety guard mounted to the housing and extending around a rearward portion of the housing, the improvement comprising:
- a bracket;
- a single wheel having an axis of rotation and rotatably mounted to one end of the bracket;
- mounting means for mounting the bracket to the safety guard with the wheel axis substantially parallel to the motor axis, and for moving the bracket and the wheel in a plane substantially perpendicular to the motor axis from a retracted inoperative position with the wheel located at one side of the motor housing for horizontal trimming operations with the trimmer suspended above ground, to an extended operative position with the wheel forward of the safety guard to engage the ground in rolling contact for supporting the cutter above the ground for edging operations.
In a line trimmer for cutting vegetation of the type having a housing, a handle extending from a rearward side of the housing at an acute angle, a head mounted to the housing for rotation about a motor axis, a flexible nonmetallic line extending outwardly from the head in a cutting plane substantially perpendicular to the motor axis, and a safety guard extending partially around the rearward portion of the housing, the safety guard including a plate substantially parallel with the cutting plane, having an upper side and a lower side and a depending flange, the improvement comprising:
- an arcuate flat bracket;
- a wheel rotatably mounted to one end of the bracket and protruding forwardly from the bracket;
- and
- means for mounting the bracket to the upper side of the safety guard for arcuate movement about the motor axis between a retracted inoperative position for trimming wherein the wheel and the bracket are at least partially located above the safety guard, to an extended operative position wherein the wheel and a portion of the bracket protrude forwardly of the housing, with the wheel located on the opposite side of the housing from the handle, for supporting the cutter above the ground with the motor axis substantially horizontal for edging operations.
