Abstract:
1. A linear-input steering mechanism for an at least partially user-powered commuter vehicle, the linear-input steering mechanism comprising: a first steering control movable only in a first substantially vertical plane; a first control arm having a pivotally retained distal end and a proximal end; a first kingpin having a pivotally retained steering arm extending therefrom and defining a first kingpin pivot axis; a first linkage extending between a proximal end being pivotally coupled to the first steering control, and a distal end being pivotally coupled to the proximal end of the first control arm; a second linkage extending between a proximal end being pivotally coupled to the proximal end of the first control arm and the distal end of the first linkage, and a distal end being pivotally coupled to the pivotally retained steering arm at a location spaced from the first kingpin pivot axis; a second kingpin having a second pivotally retained steering arm extending therefrom and defining a second kingpin pivot axis; and a tie rod extending between and being pivotally coupled to the pivotally retained steering arms.
