Abstract
A stabilizing roller for a line trimmer device that includes a housing with a cylindrical bore for receiving and mating with a ball roller. The lower end of the housing is open to allow the ball to contact the ground while in operation. The ball is maintained in the housing on the lower end using either an integral lip or a removable retaining plate. The upper end of the housing is closed with a cap designed to mate with the ball during operation. Thus, the ball is free to roll. The housing is connected to a line trimmer device by either a bolt attached to the head of the line trimmer device or a frame and attachment means connected to the extension arm of the line trimmer device.
Claims19
A line trimmer device stabilizer comprising:
- a housing having a cylindrical bore therein, a top end, a bottom end, and a vertical axis;
- said cylindrical bore extending vertically through the housing and having an inner surface;
- a top housing cover attached to said top end of said housing having an upper surface and a lower surface;
- said housing and top housing cover comprising a housing and cover assembly;
- said cylindrical bore inner surface and top housing cover lower surface defining an axial cavity;
- a ball having a substantially spherical shape positioned in the axial cavity;
- said axial cavity designed for rollably receiving and mating with the ball;
- said ball having a diameter less than the cylindrical bore diameter;
