Abstract
A shield and structure for mounting the shield to a hand held grass trimmer is provided. The generally flat shield is perpendicularly mounted to a gear box extension which is carried coaxial with the drive shaft tube. Twisting and moment forces incurred by the shield when the trimmer is resting on the ground are reduced by mounting the shield to support the weight of the trimmer generally perpendicular to the length of the drive shaft tube. The mounting structure prevents sliding of the shield on the drive tube and provides multiple attaching members to prevent rotation of the shield on the drive tube.
Claims2
A hand held trimmer having
- a power source including a first trimmer support surface;
- an elongated power shaft driven by the power source;
- a gear box operatively coupled with the power shaft, the gear box including a casting fixed thereto and extending therefrom at an acute angle, the casting being generally cylindrical and extending from the power shaft;
- a cutter head attached to the gear box, said cutter head including a cutting element driven by the gear box;
- an elongated generally flat cutter element shield having one portion connected to the casting and a second portion having a second trimmer support surface;
- and means for mounting the one portion of the shield generally perpendicular to the power shaft including first and second mating surfaces on the shield and the casting, respectively, for mounting the shield generally perpendicular to the power shaft, and means for detachably connecting the first and second surfaces together.
- whereby the trimmer when resting on the ground is supported by the first and second trimmer support surfaces, the power shaft is generally parallel to the ground and the shield extends generally perpendicular between the power shaft and the ground.
