Abstract
This invention relates to a pivotal control for engaging and disengaging the parking brake of an outdoor power equipment unit such as a lawn mower. The control is laterally pivotal from an inboard to an outboard position by the operator as the operator mounts or dismounts the unit. This lateral pivoting motion is converted by a bevel gear arrangement to a longitudinal push on the inner cable of a Bowden cable, with the inner cable being connected to a parking brake. Pushing on the inner cable in this manner causes a portion of the inner cable between a fixed rear end of the outer sheath of the Bowden cable and the parking brake to become additionally curved or bowed. The amount of this additional curvature or bow is sufficient to develop a biasing force in the inner cable that keeps the parking brake engaged. Thus, no separate biasing spring is required.
