Moveable control pedal assembly
First Claim
1. A control pedal assembly moveable toward and away from a vehicle operator, comprising:
- a mounting bracket;
at least one pedal arm;
a pedal carriage to which the pedal arm is pivotally attached;
an extender mechanism connected to the mounting bracket and including;
at least one extender rod having a threaded portion and a portion engaged to a first driven gear, the threaded portion of the extender rod engaging a complementary threaded bore in a bushing attached to the pedal carriage, the extender rod being substantially prevented from lateral movement;
a control rod having a threaded portion and a portion to engage a second driven gear, the threaded portion of the control rod engaging a complementary threaded bore in a bushing attached to the pedal arm, the portion engaging the second driven gear being laterally movable through the second driven gear and the end distal the threaded portion actuating a mechanism to be controlled; and
a driving gear engaging the first and second driven gears such that, when the driving gear is rotated in a first direction by a driving means, the pedal carriage is moved toward the mounting bracket and when the driving gear is rotated in a second direction by a driving means, the pedal carriage is moved away from the mounting bracket.

Abstract
A moveable control pedal assembly includes a pedal carriage to which a pedal arm is mounted. The carriage can be moved forward and backward via threaded extender rods which engage the pedal carriage to move it along the extender rods when they are rotated by a suitable drive means. A threaded control rod, extending between the pedal arm and a control device, such as a hydraulic cylinder or control cable, rotates with the extender rods and allows movement of the pedal carriage and pedal arm without altering the mechanical advantage provided by the pedal arm and without altering the lateral positioning of the control rod.
