Patent ID: 7788991

Claim:
A foot pedal mechanism comprising: a bracket having a track; a first shaft associated with the bracket for positioning along the track in the bracket, the first shaft having a first axis; a mechanism for causing the first shaft to be held fast in a desired position along the track; a pedal arm supported on the first shaft for swinging about the first axis of the first shaft; a second shaft that has second axis parallel to the first axis of the first shaft and threaded through-hole; a positioning mechanism carried by the pedal arm for positioning the pedal arm and the first shaft along the track in the bracket to set a distance between the first axis of the first shaft and the second axis of the second shaft; the second shaft being operatively related to the pedal arm for swinging with the pedal arm by a connection with the positioning mechanism; a structure having an arcuate track operatively associated with the second shaft such that the structure provides guided constraint of the second shaft about the first axis of the first shaft when the second shaft is swinging with the pedal arm; and a pedal arm extension that comprises a pedal pad and that is arranged for travel on the pedal arm radially of the first axis of the first shaft and has an operative connection with the positioning mechanism for causing the pedal arm extension to travel on the pedal arm radially relative to the first axis a distance equal to a change in distance between the first axis of the first shaft and the second axis of the second shaft as the first shaft is being positioned along the track in the bracket to cause distance between the pedal pad and the second shaft to remain substantially unchanged wherein the positioning mechanism comprises a rod, the rod having a third axis and a length extending radially with respect to the first axis of the first shaft, wherein the rod passes through, and has threaded engagement with the threaded through-hole in the second shaft, and wherein the pedal arm and the rod are operatively related for movement in unison to change distance between the first axis of the first shaft and the second axis of the second shaft when the rod turns about the third axis.
